Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

Germany is finally getting serious about self-driving cars

Germany cleared the way for its giant automotive industry to develop and test self-driving cars, when the upper house of its parliament approved on Friday a law setting out the conditions under which they could take to German roads. Under the law, first mooted by Chancellor Angela Merkel last year, a driver must be sitting behind the wheel at all times ready to take back control if prompted to do so by the autonomous vehicle. Germany is home to some of the world's largest car companies, including Volkswagen, Daimler and BMW, all of which are investing heavily in a technology seen by transport minister Alexander Dobrindt as the "greatest mobility revolution since the invention of the car." That's not to say that German automakers have been standing still in the face of autonomous technology. VW recently outlined its vision for autonomous vehicles. BMW has already demonstrated self-driving vehicles in the United States, and Mercedes-Benz has partnered up with German auto supplier Bosch on autonomous technology. The new legislation allows German car companies to road-test vehicles in which drivers will be allowed to take their hands off the wheel and their eyes off the road to browse the web or check e-mails while the vehicle handles steering or braking autonomously. The legislation requires that a black box record the journey underway, logging whether the human driver or the car's self-piloting system was in charge at all moments of the ride. This will be crucial for apportioning blame in accidents. The driver will bear responsibility for accidents that take place under his or her watch, under the legislation, but if the self-driving system is in charge and a system failure is to blame, the manufacturer will be responsible. The law will be revised in two years' time in the light of technological developments, with data protection and the use of the data collected during rides a key point that has yet to be fully addressed. Companies around the globe are working on prototypes for self-driving vehicles, but such cars are not expected to be available for the mass market before 2020.

The 2017 Audi R8 Spyder starts at $176,350

Audi just revealed pricing info for the R8 Spyder, which will start at $176,350, about a year after revealing pricing information for the coupe ( which starts at $164,150 in base form; the Plus starts at $191,150). In case you haven't had your coffee yet, like-equipped base cars will span a $12,000 gulf. But the 2017 R8 Spyder costs about the same as the outgoing R8 Spyder V10 equipped with an automatic (which was at the time a very expensive option), so consider that minimal price inflation. The more interesting comparison is with its platform-mate, the Lamborghini Huracan. A drop-top version of the Italian supercar starts at $267,545 in similar AWD trim with a 5.2-liter V10. Now, it is true that the Huracan Spyder makes 602 horsepower, a 62 horsepower advantage over the standard R8 Spyder with the same engine (540 hp if you are bad at math). The Lambo also a tenth faster to 60 mph than the R8 Spyder, at 3.4 seconds. (The '17 R8 Spyder is itself a tenth quicker than its predecessor, so there's that.) But, the R8 V10 Plus makes 610 hp. We're waiting to hear back form Audi on pricing for that Spyder model. In the coupe, it's a $27,000 increase over the base R8 V10. That logic would peg an R8 Spyder V10 Plus at around $203,000, or $64k less than the Huracan. In either case, you're paying a lot for Lamborghini's unique styling and tuning, although it's hard to put a price on the specialness of driving a Lamborghini. The Huracan Spyder never for a moment lets you forget you're in something fast and Italian. That being said, both are legitimate supercars. The R8 Spyder was developed alongside its Italian cousin, and features an appropriately large amount of aluminum and carbon fiber materials in its construction. Of course, like its coupe counterpart, there's no manual available for the new R8 Spyder. That died with the previous generation. The good news, for fans of open-air driving, is that the roof mechanism only adds 97 lbs to the weight of the car, and Audi kept the electrohydraulics that actuate it as low as possible. If it's anything like the Coupe to drive, and you can be sure since it's an Audi there won't be much trade-off for the open roof, it'll have a dual personality that will accommodate both daily driving and occasional track use. Sounds like a deal, huh? Related Video: Audi Convertible Luxury Performance Supercars r8 spyder r8 huracan
