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?
On the last point (though I won’t debate the others, you’re pretty much right); Where I live, there’s actually a fair few workplaces and “transit companies” that provide various shuttle offerings to make it easy for workers to commute to work without everyone needing a car. It’s great if the workplace in question doesn’t necessarily come near plenty of parking. It’s kind of like how as a kid, a school bus would pick you up, though they’ll likely choose a convenient hub area.
