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.

Watch Audi's Emmy promo, starring Bryan Cranston, Aaron Paul and Julia Louis-Dreyfus

A lot of online videos try way too hard to be funny, but the promo from Audi for the 66th Emmy Awards on Monday, August 25, shows that if you put faith in a proven group of hilarious actors, you can strike comedy gold. The short film reunites Breaking Bad stars Bryan Cranston and Aaron Paul as the proprietors of a pawnshop of rare and obscure items called Barely Legal Pawn. They have their own fictional reality show (which really needs to exist) that rips off Pawn Stars, and this segment has comedy veteran Julia Louis-Dreyfus coming in to sell her Emmy award for Best Supporting Actress in a Comedy as Elaine on Seinfeld. Louis-Dreyfus also pays the title sponsor's bills by subtly incorporating a 2015 S3 into the otherwise car-free gag.
It would ruin the video to spoil any of the jokes; you just need to watch it. Cranston actually bridges the gap here because way before he became famous as Walter White on Breaking Bad, he had a recurring guest role on Seinfeld as dentist Dr. Tim Whatley. If you're a fan of either show or just need a hearty chuckle for today, this one is definitely for you because all three former Emmy winners put in fantastic performances.

Audi billboard tracks pedestrians like prison escapees

Audi's adaptive Matrix LED headlights can actively dim and direct light around the road to make driving safer at night. Unfortunately, the tech runs afoul of Department of Transportation rules, so it isn't currently available in the United States. For an idea of what you're missing, a marketing stunt for the new A4 in Belgium is illuminating the night and making pedestrians in the intersection more visible, and safer. The only problem is, it also makes them look like fugitives making an escape. From a giant billboard near the Brussels Central Station, the LEDs from a massive Audi A4 can light up whole intersection. Whenever a pedestrian or cyclist enters the area at night, they are tracked the whole way in a radiant pillar of blue luminescence. Based on this clip, the lights look bright enough to temporarily blind some passersby. Despite the unintended consequences, the stunt is still a very visible demonstration of Audi's headlight technology. Related Video: The video meant to be presented here is no longer available.
