This question already has an answer here:
So, I’m creating a post-apocalyptic world set 97 years after nuclear war, in the former state of California, AD 2059. The Californians, compared to the rests of the wastes, have done good for themselves, creating lawful cities and towns with advanced infrastructure. Their society compares to ours at around 1880s-90s level.
A few technophiles have even gotten some cars up and running again, and use them to travel quicker in between cities. But not inside of them. Motor vehicles have been outlawed for use within city gates, so my question is, what would be a logical basis for cities in post-apocalyptic California to outlaw motor vehicles?
