Adam Elliott, 25, was driving through Newcastle to deliver a Ford StreetKa to a buyer when he was stopped by police who say he was distracting other drivers.
Elliott, who is 6ft 7ins tall, was issued with a court summons where he will face a charge of careless driving.
He said: “My head was crammed too low to see with the roof on so I put it down.
“I got a lot of attention and had a laugh waving at people who tooted their horns at me.
“But I wasn’t a danger.”
After being pulled over, Elliott took to his Facebook profile where he posted pictures of himself behind the wheel of the StreetKa.
He wrote: “I get a section 59 and summons for careless driving for being too big for my Ka?
“Anyone know any decent solicitors that deal with driving?”
