Driving with shared cars, Uber, hybrids, evs, and self-driving cars doesn't fix the one and ultimate problem with cars in cities: space. A person walking needs maybe 0.5m². Self-driving electric Uber still needs ~50-60 m² of space per vehicle in moving traffic. Plus parking. And if we allocate enough space for people to drive in the first place they can only drive to places. The distances grow too long for biking and walking.
