It would depend on how bad travel was without cars yesterday. Historically, it was horses which must have been really bad. I think if they knew back then about speeds, traffic, and conditions they still would have done it. Parts of China and India have proved it quite recently (last 50 years).
Now if we had most people in high density housing, good transport (both public and private), and online ordering/​delivery then maybe cars would be very restricted.
