Nice, I waited until like 26 to get my permit, mostly with going to school down town and the buses I didn't really need to.
That and I have a healthy fear of driving.
One bit of advice, when I was practicing there weren't any one way streets, but when I took the driving test there was and it resulted in a instant fail due (there are a couple of things that result in instant fail) to not knowing a specific rule in that I never come across because I never had drove down a one way street.
