@Ria: No, I stopped 4 times, 3 to rest and 1 to go grab lunch. Still was rough on me doing it alone and I've been recovering from being ill last week.

@Sammi: Smooth sailing figuratively of course, the car is powered by gasoline and drives on a road.

I didn't know that your car was wind powered...

Yeah, but then you'd have to stop to shut it again, and they'd catch you up and erm.. deal robustly with you..?

Wow, 11 hours, not all in one go, I hope..? 

I must be geting old, these days I can't go for more than two or three hours without stopping for a drink and/or the loo, and anything over about 300 miles calls for an overnight stop

Drove back home for fall break, took me about 11 hours. Chicago traffic was really bad but I managed to escape alive and the rest was smooth sailing.

I've toyed with the idea of putting a light bar on the inside of my trunklid, so when someone is has the high beams on behind me at night I press a button under the dash and the trunk pops open and the light turns on....

Heh. That would work

 Back when I was still able to drive my old Police car , I used to use the pillar mounted spot light for the same purpose . It has a 100w halogen sealed beam in it ! 

This may solve your problem

It's probably the same reason that they feel the need to keep their foot on the brake pedal at red lights or in traffic queues
