Frankly - I agree with this take.
If anything - my opinion at this point is that cars were a mistake in vehicle sizing caused by internal combustion engines.
For the vast, vast majority of ubran transit, something akin to a bike in size seems to make more sense.
We see this already in urban regions in India/Asia where scooters are the predominate transportation method, and I think even traditional scooters are heavy enough to be problematic.
But a class 2 ebike (so throttle with no need to pedal) can weigh as little as 40lbs (20kg), and go 30 miles at 20mph.
It's insane that we're not designing urban transit for bikes at this point. Much better density, much safer, much easier to store and park, much cheaper to operate and license.
