How driving a car is different from taking public transport?

Most of the time, when I have taken public transport, I have gotten tired. It has always seemed like a total hassle for me to take and use public transport. This is why I decided to contact the best-used car dealers in Japan so that I could get myself a good car at affordable rates. Driving a car was very different from riding a subway train altogether. It was much more comfortable plus now I did not need to walk miles before I could take a ride. Another thing I realized was that driving was very relaxing for me. What other differences might be there between the two modes of transport?
