These past 10 years: I really loved long trips from NYC to Pittsburgh, driving Marietta (TheDivaden/Eurodiva) to her parents for Christmas vacation the most. 9 hours: talking, listening to music, the scenery (including the odd bit of roadside wildlife (not roadkill)), and the knowledge of the destination is sometime soon.
And the odd trips from NYC to Boston as well.
And even before these long trips, I always felt comfortable behind the wheel. Just as long as I had plenty of CD's and an NPR station to listen to.
I drove countless of thousands of miles for various jobs: a shuttle bus for a college; a security vehicle at the Natick Mall. Driving around and listening to the radio and getting paid as a sweet deal.
Not to mention the time I drove some very large track vehicles while in the army. An M992 Field Artillery Ammunition Support Vehicle (FAASV).
Absolutely hated driving for the post office (a temp job). Trying to concentrate on where the next part of the route was too stressful. And like most people, I too was frustrated by traffic and other drivers.
