I go to Fort Lauderdale every year and drive naked most of the trip, when I pass trucks I drive a little quicker by them so they really can't look it, plus I have a little darker tint on my windows. If he didn't get your license plate the police can't do anything,
I also hope / believe that if the driver showed his video to the cop, he would have been done for dangerous driving, or whatever the equivalent is .
I do agree with Olly though, having your pants around your knees/ankles and getting undressed while driving is unsafe.
Many times while driving past these lorries I glance up into their main drivers mirror and 99% of the time I only see the side of the drivers head which shows s/he is concentrating on the driving and wouldn't realise if I was driving past him/her nude.
I enjoy driving nude to and from work in the summer practically everyday. In the morning I dont even bother getting dressed at home, I just toss my clothes into the car and hit the road. I'll strip naked in the car as I leave work, when I get home I just grab my clothes and head into the house. I'm on the interstate for about 30 minutes each way, it's rare that any truckers acknowledge that they have seen me naked.
I tend to take off my clothes when driving during the summer because its just too hot here. Im usually stripping down the minute i leave work. Most people are unaware and have no idea, unless a truck or semi is next to me who probably gets a view.
