I just posted in the introduction area as I am new to this site and pipe smoking, but I just wanted to say that for me having a pipe while I drive is my favorite time to smoke the pipe. I live a life that is very busy sometimes to busy, and my hour long commute on rural roads is often the only time I get by myself to relax. The first time I tried to smoke the pipe while driving I ended up having to pull over to load, pack and light the pipe. Now I like others have mentioned, have figured out to pack and char light before leaving. Then when in the car and ready for the pipe, I just have to light and puff. I'm a former cigarette smoker and I have to say I think the pipe is easier to handle while driving, as you don't have ash to constantly deal with. If the pipe goes out you can wait till it's safe to relight, but the hot ash of a cigarette won't wait.
