Simple: I fucking hate driving. I hate the smell, I hate the noise, and I hate the stress. Thr environmental impact isnt exactly a plus point either. You could say that I'm lucky to live in a place with good public transport, but I actively sought out a place with public transport because I didn't want to rely on a car.
Final nail on the coffin: I developed Menieres disease, so I am prone to intense vertigo attacks at short notice - I couldn't get a license even if I wanted one.
