That smoking while driving my Jeep with the doors and windows off is a most enjoyable experience!
The wind helps keep the pipe going...but that also means a bowl goes much quicker! On the other hand...I only had one relight early into the bowl (after a semi came by and sucked the "cherry" out of the pipe dumping hot ash all over me in the process) and smoked it down to a fine white ash! Zero dottle left!
