Lexus, Mazda, and Yamaha wow Tokyo with stunning concept cars

Mazda The RX-Vision. Mazda calls this design language KODO. 11 more images in gallery We make no apologies for our love of the concept car at Ars Technica, and this year’s Tokyo auto show has just delivered another fix. Home turf for companies like Mazda, Toyota, and Yamaha means they usually push the boat (or in this case the car) out with something special, and 2015 is no exception. First up is Mazda’s RX-Vision, which announces to the world that the company has not given up on the rotary engine. The RX-Vision is a front-engined, rear-wheel drive sports car that has RX-7 fans salivating at the prospect of a replacement for the iconic car. Although Mazda says it has no plan to put the car into production, we wouldn’t be surprised if a groundswell of popular opinion eventually changed its mind. Read 2 remaining paragraphs | Comments

Tesla takes the wheel: driving a Model S hands-free

Elon Musk isn’t happy just introducing an automobile and walking away to work on next year’s model. Instead his company continues to offer over-the-air upgrades to current vehicles. The latest software enhance is landing in its electric cars tomorrow with a slew of new autopilot features . They won’t drive you around town, but will make highway driving and parking a bit easier. While the new Autopark does exactly what you would expect, Autosteer is a bit more ambitious. With it, you’re supposed to be able to go for miles on the open road with it doing most of the heavy lifting. The car tracks lane markers and uses enhanced GPS data to keep the car from launching off into the median. I had a chance to drive a Tesla on the highway with its new ability — without using my hands — and it was outstanding, but also a bit weird. The big feature, Autosteer, is less autonomous driving and more of a very advanced version of cruise control. For those looking forward to getting a robot car to drive them to work, Musk expects Tesla will have a fully autonomous vehicle ready to go in three years. In the meantime, this new autopilot feature will maintain the cruise control speed while keeping a safe distance between itself and the vehicle in front of it and stay in its lane. It’s a gradual step toward the future that’ll make commuting less of a pain. After setting the mode in the car’s updated UI and double-tapping the cruise control arm, the car does the driving for you. It’s an eerily smooth transition. If the vehicle determines you’re not centered in a lane, it adjusts itself without jerking the vehicle. After that, I removed my hands from the wheel and the Model S tracked itself along Interstate 280 better than most of the other drivers on the road. It had no trouble with meandering corners. It kept a safe distance behind the car in front of it (something you can manually adjust if you would like more cushion). Adjusting the speed was a matter of flipping the cruise control arm: up to go faster and down to slow down. Meanwhile you just sit there. Because you’re hurtling down the freeway, you’re still paying attention, but it lowers the stress level a bit. If you’re stuck in traffic, it takes the pain out of the stop-and-go experience because it does it for you. You’ve gone from driver to driver/passenger. This is the first step to the pure passenger experience of truly autonomous cars. While it’s cool, Musk stresses that this is a public beta of the feature and that drivers should keep their hands on the wheel at all time: “We want people to be quite careful.” That warning becomes an audible alert in the vehicle when the lane markers become faded or another car slides into your lane. At that point, you’re reminded that, yeah you’re still the driver. The entire Autosteer system is built around the vehicle’s confidence that what’s about to happen is safe. If the roadway is less than optimal, you can’t engage it. If while engaged, it detects something out of the ordinary, an audible and visual warning inform you to take control. If you ignore that, the warning gets more persistent and the system will eventually slow the car down and bring it to a complete stop. That confidence spills over into the Auto Lane Change feature. While in Autosteer, I attempted to automatically move to the left lane. A vehicle was approaching at a rather quick pace on my left and the car wouldn’t complete the move on its own. At that point, it got a little too careful and wouldn’t automatically move itself into any lanes. After having the passenger turn the feature off and then back on again (just like a router, but speeding down the highway), I was switching lanes (when it was safe) without checking my blind spots or even grabbing the wheel. For someone that’s completely obsessed with safe driving, it’s unnerving letting the car take over like this. But with a quick brake tap or slight turn of the steering wheel, I was back in control. While existing the freeway, I was able to complete a few automatic lane changes, but when the car detected a car that was behind and to the right of me, it again wouldn’t go on its own. I accelerated and pulled into the right lane as I would with any other car. The car errors on the side of caution without making you feel like you’re being coddled. Yes, it’ll be abused (get ready for more texting and driving), but even while driving down a surface street, it avoided a bus sticking out in the road. But it’s not even close to infallible. Hence the repeated warnings from Musk during a briefing. It also has difficulty with sharp turns and inclement weather conditions like rain, snow and fog. Tesla is adamant that the feature is “hands on” so you’re supposed to keep those mitts on the wheel. So don’t starting updating Twitter while you’re supposed to be driving. Yet, It’ll get better as more and more Teslas drive in autopilot mode and feed road information back to companies highly detailed mapping system. The update also brings enhanced versions of traffic-aware cruise control, side collision warning, vehicle hold (keeping the car rolling on inclines), Autopark and better climate control that cools or heats the interior quicker without using more energy. All of that is wrapped into a brand new UI. Tesla is still a few years away from getting us from point A to Pint B without our interaction. But in the meantime, it’s tackling the commute, the worst aspect of the driving experience by letting its cars take the wheel. It’s a smart move and for anyone that sits in a traffic, a welcome relief. Source: Tesla

Linux 4.3 Bringing Stable Intel Skylake Support, Reworked NVIDIA Driver

An anonymous reader writes: Mr. Torvalds has released Linux 4.3-rc1 this weekend. He characterized the release as “not particularly small — pretty average in size, in fact. Everything looks fairly normal, in fact, with about 70% of the changes being drivers, 10% architecture updates, and the remaining 20% are spread out.” There are a number of new user-facing features including stabilized Intel “Skylake” processor support, initial AMD R9 Fury graphics support, SMP scheduler optimizations, file-system fixes, a reworked open-source NVIDIA driver, and many Linux hardware driver updates.

Faster booting, smaller footprint make Windows 10 an easy upgrade for old PCs

A whole bunch of people are going to upgrade to Windows 10. Not everyone . But when you offer free Windows via a nag message delivered to over 80 percent of the user base, you’re going to attract people who wouldn’t have driven to MicroCenter to buy an upgrade DVD. Especially if you bought an eligible PC in Windows 7’s heyday, you will probably be installing the new OS on five- or six-year-old hardware that has long since been forgotten about by the company that sold it to you. Or maybe you bought something during the post-Chromebook era, where Windows PCs dipped back into netbook territory in their quest for a low price tag. We installed Windows 10 on a few of these kinds of systems to see what you can expect, at least if you’re comparing a clean install to a clean install. Current users of both Windows 7 and Windows 8 should expect to recover a few gigabytes of drive space, a few megabytes of system RAM, and a few precious seconds of boot time.

How Uber Surge Pricing Really Works

minstrelmike writes with this analysis from Nicholas Diakopoulos of the Washington Post: At the core of Uber’s wild success and market valuation of over $41 billion is its data and algorithmically fueled approach to matching supply and demand for cars. It’s classic economics, supposedly….but is Uber’s surge pricing algorithm really doing what they claim? Do surge prices really get more cars on the road? My analysis suggests that rather than motivating a fresh supply of drivers, surge pricing instead re-distributes drivers already on the road. Adds minstrelmike: The writer goes on to analyze 4 weeks of pricing info from 5 areas in D.C. and plotted prices versus wait times. “Price surging can work in any of three ways: by reducing demand for cars (less people want a car for a higher price), by creating new supply (providing an incentive for new drivers to hit the roads), or by shifting supply (drivers) to areas of higher demand.” It moves current drivers from one side of town to the other. It does not put new drivers on the road. It can’t because the prices change every 3-5 minutes.” Read more of this story at Slashdot.

NVIDIA’s GeForce GTX TITAN X Becomes First 12GB Consumer Graphics Card

Deathspawner writes: When NVIDIA announced its GeForce GTX TITAN X at GTC, no one was surprised that it’d be faster than the company’s previous top-end card, the GTX 980. But what did impress many is that the company said the card would sport a staggering 12GB of VRAM. As Techgage found, pushing that 12GB is an exercise in patience — you really have to go out of your way to come even close. Additional reviews available at PC Perspective and AnandTech. The latter notes, “…from a technical perspective, the GTX Titan X and GM200 GPU represent an interesting shift in high-end GPU design goals for NVIDIA, one whose ramifications I’m not sure we fully understand yet. By building what’s essentially a bigger version of GM204, heavy on graphics and light on FP64 compute, NVIDIA has been able to drive up performance without a GM204-like increase in die size. At 601mm2 GM200 is still NVIDIA’s largest GPU to date, but by producing their purist graphics GPU in quite some time, it has allowed NVIDIA to pack more graphics horsepower than ever before into a 28nm GPU. What remains to be seen then is whether this graphics/FP32-centric design is a one-off occurrence for 28nm, or if this is the start of a permanent shift in NVIDIA GPU design.” Read more of this story at Slashdot.

Federal Study: Marijuana Use Doesn’t Increase Auto Crash Rates

An anonymous reader writes: After the legalization of marijuana in multiple states around the U.S., many are worried about a corresponding uptick in car crashes as people drive while under the influence of pot. But according to a new federal study (PDF) commissioned by the National Highway Traffic Safety Administration, those fears seem unfounded. They report that after adjusting for other factors (people who tend to drive after using marijuana also tend to be more crash-prone in general), there was no statistically significant increase in crash rates by drivers who tested positive for the drug. It’s still a bad idea to drive high, but driving drunk is far, far worse: “One substance was shown to have a major influence on crashes: alcohol. The study confirmed the enormous danger of drinking and driving, even after age and sex adjustment: drivers with a 0.05% blood-alcohol level were found to be twice as likely to be in a crash. For a person weighing 180 to 190 pounds, that could be a single can of beer, glass of wine, or shot of liquor. At 0.08% (two drinks), the likelihood is quadrupled, and at .20% (four drinks or more), the risk is higher by 23 times.” Read more of this story at Slashdot.
