Waymo had a 20 year advantage, but Google lost many key people there in the meantime as Larry Page didn't want to launch partial self driving.
I think both approaches are great and I wouldn't want to choose between the 2, just be a happy user of the end result of the competition.
any source for that?
That's the responsible thing to do.
But at the same time people understand that on a highway Tesla Autopilot is safe enough to be used on a long boring road, and dricers generally feel less tired (and can focus more on the harder parts of the road).
In all seriousness, I like Karpathy and his work. Seems like a good guy. Not sure why you'd want to work to enrich a guy like Elon Musk though.
If you look at the alternative (Dieselgate), which is killing millions of people every year thanks to air pollution (sadly I'm highly affected by it, trying to not go near any polluted area is what my life is about at an age of 37), I'm happy for Elon Musk and I hope Tesla's mission will succeed as soon as it is possible.
