You have to think forward to understand Musk.
Which would you prefer? Going at 100 km/h with autopilot on today's highways, sharing the road with people without autopilot, or going at 250 km/h with autopilot on a highway where everyone else is also on autopilot?
We will have to follow a likely tortuous path to get from now to then, but I am totally convinced we will get there.
- lorenzhs 10y agoThe problem with that is that aerodynamic drag grows with the third power of speed, so going faster requires much more energy, even after accounting for slipstream benefits that a self-driving mechanism could exploit. For some numbers, see https://www.quora.com/How-long-can-you-drive-a-Tesla-S-P90D-at-maximum-speed-on-a-single-full-charge https://www.quora.com/How-long-can-you-drive-a-Tesla-S-P90D-... . The top comment is about racing, but the one below it lists 300Wh/km at 160km/h and 380Wh/km at 180km/h. That's a quarter more energy per km (!) for going 20km/h faster.
