bikes are much easier to take care of, repair, change tires, easier to park in the city... also much better for the summer time, as you can really enjoy your ride and relax and go through short passes like a park alee or smth. in winter thou, i would prefer driving a car, because of the weather and all the colds one can get. also if you have a child the car is much comfortable. all in all, one should have and use both a car and a bike, depending on the weather and situation.
