Depends on your job and where you live. In the big city you generally don’t need a car. Same if you have an office job. But I wouldn’t want my colleagues to drive me around every day if I were a craftsman or sth like that…

Theory examn takes quite some practice. You got to repeat those questions over and over again for weeks. You’ve probably not put enough effort in. Get that computer program and simulate examns until you’re able to comfortably do it. If you can’t do it, maybe those summer camp driving schools are more your thing. You’ll practice together with other people for like 2 weeks straight. It ain’t cheap, though.

If you’re from a different country, maybe my advice doesn’t apply. Ultimately I think not everyone needs a drivers license.
