I'm actually curious about the bus, too. Sounds weird. But I trust his judgement, I'm sure it'll be great. He has a track record, you know.

Regarding missed promises, if you're saying that as if to suggest that what he's promised isn't nonetheless coming true at a pace faster than anyone else could have possibly delivered, I think you're wearing blinders.

Regarding "most difficult".......are you aware of other companies working on something as technologically and logistically and legally challenging as SpaceX and Tesla????

So you're saying that, if I promise you I'll give you a thousand dollars in a week but then I give it to you in two years, I haven't broken a promise?

I'm saying if you promise me you'll get to Mars in a week, and do it in 10 years instead, I'll still consider you a pretty astonishing person.

Google's doing a lot better on the whole self driving front.

At least in terms of fatalities per mile.

Google has a handful of their engineers driving around in weird-looking minicars.

Tesla has thousands of regular consumers driving all over the world in sleek sedans.

Let's see which bet pays off better in five years' time.

The weird minicars are not what they've been road testing. The ones they've been road testing for ML look like regular cars.

And they have yet to hit a pedestrian or decapitate a driver with a semi. Be real; Tesla's is basically a smarter cruise control. It can't actually deal with complicated scenarios.

By measure of "Hard" technology... Uber is just software.

Electric Cars and Reusable rockets are engineering marvels, not nifty software. That's difficult.
