Plenty of people don't drive for plenty of reasons. Economic and environmental issues are probably tops.
But if your like me - I don't drive, too poor at 16/17 to learn, too poor after that to buy a car.
Then when I finally had a job & had my learners, I went through the windshield in a car accident.
You might be surprised at how many people have been in serious accidents and don't want to drive, and it's not about hurting you, you become extremely concious of cars being lethal weapons, I'm terrified of hurting someone else.
But I do wish I could drive, it's like being handicapped
