Something extra
While driving nude why not pull up, get out of your car and lock yourself out (I'll suggest ways if you want) just for a dare. So there you are: naked, locked out and some distance from home! You could call out a breakdown service or walk, get a lift or catch a bus home to get your spare key - still naked
Of course that is too risky for most of us. But there are variations. You can do it with a friend using two cars. Park one car and both get into the second car. Now drive a short distance , get out and walk back naked to the first car. It is best planned with a map showing useful footpaths. If you only have the one car take the spare set of keys, which are hidden somewhere. Drive a short distance. Lock yourself naked out of your car and go retrieve the spare keys.
