Are private cars the primary means of getting around any city today?
I would have thought it was already totally impossible to 'get around' a city like San Francisco, London or New York by car. Where on earth would you park securely at each stop? I can't imagine ever even attempting to drive into a major city. Maybe if I had a very specific plan of getting to a particular hotel that I knew had a car park with spaces that had enough headroom for my car, etc. But driving into a city to just 'get around' without a plan? Surely that's suicide?
I don't think any of the vehicles in a city are private cars - aren't they almost all taxis and commercial vehicles making deliveries?
