Comma.ai makes your car semi-autonomous for $999

At TechCrunch's Disrupt conference in San Francisco, Comma.ai founder George "Geohot" Hotz announced the launch of the Comma One semi-autonomous driving device. Hotz said at the conference that his company has worked on the Comma One for about a year, and it will be available at the end of the year for $999 and a $24 per month subscription fee. But aside from the reasonable price, which TechCrunch points out is possible thanks to off-the-shelf components, the appeal here is that it's an add-on to an existing car that can be installed at home by the car's owner. This gives people with normal cars the opportunity to have semi-autonomous features without having to buy an entire vehicle... that is, if you have a Honda or Acura with lane-keeping assist, since Comma One is currently only compatible with those vehicles. It remains to be seen if the company will add more vehicles to the list over time. The device is roughly the size of a large cell phone or aftermarket navigation system, and it has a screen on the front and a pair of cameras on the back. The computer combines information from the device's cameras and the car's radar sensors to understand what's happening and how to respond. Hotz explained at the conference that this system is similar in capability to the Tesla Autopilot system, and will be able to complete a drive, start to finish, without the driver having to touch anything. He did however emphasize that the driver must still pay attention in the event something goes wrong, comparing the experience to watching a young student driver. Hotz told TechCrunch that the device should start shipping at the end of the year. He also said that owners of compatible Honda products in the San Francisco area are eligible for beta testing, and can get involved by emailing him at george@comma.ai. So if you've been pining for a semi-autonomous vehicle of your own, but couldn't spring for a Tesla, you won't have to wait much longer. We should point out that we don't know yet how well the system works, though we hope to find out soon. Related Video:

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"

We drive the Acura TLX-GT racecar

Don't break the car. As you can tell from the video, that's the theme of the day at Gingerman Raceway in South Haven, MI. After two short lapping sessions in the Acura TLX-GT fear gave way to familiarity, and a second theme emerged: this is awesome. The anxiety was appropriate. There are only two TLX-GTs in the world, and both were at Gingerman that day. A mishap would potentially put either Ryan Eversly and Peter Cunningham out of contention for the subsequent Pirelli World Challenge race. I did not want to be that guy. But back to the awesome part. The TLX-GT is barely TLX, but more Acura that you might expect. The wheelbase, roof, and doors are all stock dimensions, although all the bodywork is carbon fiber. Out go the front MacPherson struts, in goes a special double-wishbone suspension. All-wheel drive comes from an XTRAC six-speed sequential transmission originally developed for Dakar Rally vehicles. The side mirrors are stock. Under the hood lies a 3.5-liter twin-turbo V6 with a stock block, head, crank, and throttle body. "Under the hood" is a generous term, though, because half of the engine sits inside the cabin. The front end of the block is aft of the front axle - the rest of the hood is taken up with radiators and hoses. To service the turbochargers, the RealTime mechanics remove the top of the dashboard. The front-mid engine location pushes the driver's seat back to the B-pillar, so you sit like Hightower from Police Academy. Only with less visibility. This does not calm the nerves. Nor does the din of 600 or so unmuffled horsepower. My first laps were understandably timid. But the TLX-GT is actually easy to drive. You get used to the low, rearward seating position almost immediately. Once rolling you don't need the clutch for shifts - just bang the right and left paddles to go up and down. I even became accustomed to the acceleration. At more than 3,000 pounds curb weigh the TLX-GT is quick, but not as explosive as cars like the Chevrolet Corvette Z06. Where the TLX-GT blows away road cars is in grip and braking, neither of which I fully exploited. The brake pedal is so hard you feel like you're standing on it just to get the pads to bite. Once engaged, they're like an endless well of deceleration, with ABS somewhere down at the bottom of the abyss. Second lapping session over, car returned intact and adrenaline high in full effect. I had the uncontrollable urge to get back behind the wheel. I mean, I barely had time to get up to speed.
