NVIDIA CEO Interviews Tesla’s Elon Musk – Video

MAR 24 2015 BY MIKE ANTHONY 3

NVIDIA’s CEO, Jen-Hsun, interviews Tesla Motors CEO Elon Musk in the 22-minute video posted above.

We were sucked into this video within the first 30 seconds by the commentary of Jen-Hsun.  Turns out he loves Tesla.

This video is packed with all sorts of information in regards to vehicles, including autonomous driving.

Musk compares autonomous driving vehicles to elevators today. Push a button, and it does exactly what you want it to do.

Imagine if your vehicle drove you wherever you wanted to go in a much safer manner than you can.

Check out the video for more on Tesla and autonomous driving.

Why is there no backwards looking radar? What happens when the autopilot wants to pass a slow moving car ahead of you on the highway, and there is another car traveling at an extremely high rate of speed in the left lane beyond the limited range of the sonic assist sensors in the rear? How can the Tesla Four System safely change lanes with only short range sonic assist sensors in the rear and no backwards looking radar?

Almost certainly it can’t. It has been pointed out in at least two articles I’ve read that the sonar’s range is too short to detect cars approaching with a difference in speed faster than a jogging pace. That’s very likely why the “automated lane change” feature hasn’t been enabled in customers’ cars. And assuming that’s true, then this isn’t anything that can be enabled by a wireless software update. The hardware, apparently, isn’t up to it.

Google’s self-driving cars use a rotating lidar (laser scanner) sensor mounted on a roll bar above the roof, so it can scan in every direction. I don’t know whether or not a truly functional “autopilot” will require that, but certainly it needs better sensors scanning the rear and sides than very short-range sonar.

Clarification: The sonar detection range is too short to allow the autopilot to sense fast-approaching cars soon enough to change the autopiloted car’s direction; soon enough to steer it out of the way of the approaching car. Sure, it can sense a fast-approaching car when it gets very close… when it’s far too late to react.
