The thing is riding bikes is fun and for some their riding is more fun on the road. Windy mountain roads are the best roads for fun riding.
I want to be able to break hard without sliding, I want to corner fast and with confidence, and I want to not deal with a bumpy road surface. The road is also usually just faster if you are riding for transportation or want to do a lot of milage.
Also not everyone has a car.....................
