If this is used primarily as a commuter vehicle then many of those those in a big city will be parking their vehicles in a much cooler parking structure and then in the garage once they get home. I imagine that'd help mitigate the problem assuming you don't live in an area with high heat AND high humidity. I know here in Indiana shade from the sun doesn't make things much cooler :P. (but then again others have to deal with that problem year-round)

I agree! Such a film would be about 500 years ahead of its time anyway...people are still far too concerned with whose ass it is and why it was farting :D.
