My car is just as reliable as it can get and I resort to using it almost all the time just because of its reliability. I am sorry but it is just more convenient and secure to sit through the traffic. Commuting by public is extremely tiring, you need to stay on alert and also there is a higher possibility of getting sick. I eliminated by sick days almost to zero when i switched from using a sub to a car. And it is worth every euro I spend on gas and parking.
