I've been on MN for long enough to have seen many of these threads. People who drive accuse those who don't drive of laziness/CFery, non-drivers refute by saying they can do everything they want to without driving. Up until not too long ago, I didn't have my license, so I'd like to think I'm well-placed to comment from both sides so to speak, and my summary is this: while I don't believe a person is any less worthy of respect for not driving, I do believe that if you can afford to and there are no medical reasons preventing you from doing so, learning to drive is absolutely worth doing and will likely open up a world of possibilities. Whether or not you choose to own a car at any given time is a different matter, but my reasons are as follows:
1.) You can live and work anywhere you choose
As a non-driver I became accustomed to organising my life around the availability of public transport. I didn't always find it limiting - I just accepted it and because I lived and worked in a city I got by. But once we moved to an area where public transport was adequate but not great, I discovered how limiting not driving actually could be. I decided I wanted to be able to live wherever I chose and be able to get around independently, and although I live back in the city now I know I can move wherever I please and take a job wherever because I'll always be able to get there. My in-laws don't drive and are always bound to areas where there is a bus or train route, and they really regret this.
2.) You can schedule your time as you please
When I didn't drive I became used to checking bus and train times and scheduling my activities around them. Public transport can be fine for getting from point A to Point B, but routes often don't connect, making multiple stops difficult or sometimes impossible. Now I find it amazing that I can go to a friend's house, do my shopping, go to a park and to the doctor all in one go. Of course, some would say they have all of this within walking distance or on one straight journey, but that would be because of a concerted choice to live in one area and if something changes e.g. bus routes, it would really throw this off like it did for me previously. If I feel like going somewhere now, I can just go, which still feels amazing to me.
3.) You can help others by driving
This was a big one for me. My DH has always driven and because I didn't drive, I could never do things like share driving on trips or pick him up from the station. I didn't realise until I started driving just how tiring it is to do long stretches of driving on your own and DH certainly appreciates that I can pick him up from work like he has done for me. I remember pre-lockdown, not long after I got my license, a colleague got sick at work and asked if I could drive her home. I was so pleased I was able to do that because just a few months before I wouldn't have been able to! I've also been able to drive elderly relatives to appointments which again I would never have been able to help with.
I really struggled in learning how to drive and felt close to giving up many times. I figured life was manageable without a license and certainly it can be. But my quality of life and the choices and freedom I've gained by driving is something I couldn't have understood before driving. Hopefully my post might motivate people like me who really struggle to drive. You can of course accommodate your life around not driving, but in the overwhelming majority of locations driving will equip you with so much more flexibility and choice as it did for me
