I love driving nude. I do it often in my jeep. If you watch other drivers, they really don't pay attention to other drivers, so I often just drive along, sometimes even through town. I always keep some shorts and a t-shirt handy in case I have to hop out of the jeep. but essentially, I just do what I do. The only time I throw the shirt on my lap is if I get in a traffic situation where a school bus ends up next to me. Colorado is great for the mountain drives as well.
Agree on other drivers not paying attention. Went to camp (75 miles each way) for an abbreviated weekend to compete in the annual poker shoot and got stuck at a red light in the left lane on the way home while driving through town. Driver next to me was in an SUV and could have easily seen I was nude but never bothered to look over.
During the drive I did notice a couple of others driving shirtless but of course have no idea if they were nude. They were in older muscle cars that probably dont have air conditioning so it made sense. I am in a new Honda Civic that doesnt look the part, although the A/C is out so driving nude isnt just nice, right now it is a necessity.
