I’m 25 and I don’t have a drivers license. I mean, I’ve never really felt the need to go and get one. Public transport is usually the fastest option where I live, and it takes a lot less responsibility to use it.
But most people would still prefer driving, rather than using the public T. Why?
As the simplest catch all to your question:
People prefer cars when they do not have access to adequate public transit.
If the transit is unsafe, untimely, or unsanitary, then it is not adequate. I live in an area of the US with a robust transit system comparatively and even it isn’t adequate. You don’t need a car to get pretty much anywhere but the travel times are at a minimum 2x due to how sparsely things are scheduled off peak times. They’re a bit closer during peak times though.
I honestly miss the free time I had while taking the buses and trains to read news or play games, but since work requires quite a hefty list of materials, and can randomly shift during a day, I need the mobility of a personal vehicle these days.
