The Jetsons season 3 episode 4
Invisibly Yours, George
It seems that Orwell Spacely, Mr. Spacely's nephew, is the company's inventor. George becomes the company's Guinea Pig. Just when the patrolling police think no one breaks the 500 mph speed limit, they see a car driven by a man without a face. The new invention doesn't clean people like it is supposed to, it makes them invisible!
