I think it’s a good idea. Not only are cars bad for the environment, but they’re also very expensive for students, so if we can reduce the number, that’s great.
Personally I’m going to take my test as soon as I’m ready (I turn 17 and will start learning in a few months) but I’m not going to buy a car until I’ve finished university, which will be at least the age of 23-24 for medicine. This is purely because I don’t have the money to spend on a car right now AND if I wait a few years, my insurance will drop massively.
I don’t think my plan would change based on where I live (within reason, if I lived in a typical town or city, etc.) but it would definitely be more useful to live somewhere with more public transport and I would probably take that into account when choosing where to live.
Better for students, better for the environment, and probably less crashes as well, so yeah I think it’s a pretty good idea.
