Seems to me like a terrible waste of time and money. 75% of women wear slacks or jeans these days, most of the ones who wear skirts wear panty hose which is about as exciting as looking at slacks. The ones they actually see with bare legs cant see much more than legs, its kinda dark where the goodies are, That means about 1% of the camera shots being only half decent.
Bring back non air conditioned cars and flared skirts and women wearing garters and nylons and I will drive my big rig next to them anyday and pass on the upskirt cameras.
Perhaps one of the reasons some women wear slacks or jeans is because that way they don't have to worry about men trying to get a peek at their privates.
