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?
Very much depends on the country you’re in too though. I live in a 1000 people village and “bus to nearest train station -> train(s) -> bus to destination” beats car in terms of speed as soon as my destination is more than ca 30km away.
Reaching the nearest grocery stores takes about 10 minutes by car (incl. finding a parking spot) and 15 by bus, so it’s not a huge difference either.
It is a huge decrease in flexibility though. The busses will only drive every 30 minutes or 1 hour, depending on the time of day.
