#3This makes total sense. Uber & Lyft lowered the barrier to entry for private transportation. Instead of paying $20,000 for a car, I only need $10 and I can ride in comfort from lower Manhattan to Brooklyn.

or just ban Uber and Lyft

#5Perhaps carpooling hasn't been incentivized enough: the current in-app economics for 'pooling' appears to be an increased time to destination but decreased fare (+/- social interactions with driver and passenger(s)). If congestion is a function of cars on road, car size, number of passengers, and path to destination, then perhaps shorter rides with more passengers in smaller cars should be incentivized more. This seems to lend itself to toll-roads/congestion-charges for different locations; this may be a gateway to a managed congestion area that is served exclusively by human-driver ride-share vehicles - could this improve congestion in those areas?
“Why get on a bus with 50 people when you can get into a car and maybe if you’re lucky, you’ll be the only person in it?” Demand for "personalized" transport is here to stay.

#7Solution: Toll roads.
The freedom of travel now being open to all, you declare 'Tax the poor! They're clogging up the roads.'?
If anything I see this as a remarkable step forward for equality.

#10Autonomous fleet parking has all the 3D density advantages of robot parking structures[1], but at dumb concrete prices. There's no aisle because there's no "random access" of a particular vehicle. No extra headroom (because they're identical) extra width (because they're precise), ventilation (because they're electric), or even lights. It's the best of both worlds.
Where land is cheap, simply drive the cars along a space-filling curve in a parking lot. One possible path is a double-spiral. Picture these lines[2] as the curb (except there's no curb, or even painted lines).
The spiral path is simple enough to calculate. One can rotate the whole spiral as viewed from above, growing and shrinking it and "wear leveling" across the entire paved surface. And the technique should generalize to any shape parking lot.
I expect writhing double-headed masses of autonomous cars near urban centers soon.
This design eliminates entirely any 3D architecture, at the small expense of some wasted space in the center determined by the turning radius[3].
Anyone know the most efficient shape would be in 3D (geometrically and structurally)? A helix is the obvious extrapolation, but I'm not convinced it's optimal.
