Police in Brighton and Hove are putting a Smart car through its miniature paces in a three-week trial to see if it can cut through congestion.
PC Dave Page has already given the unusual-looking two-seater a whirl at police headquarters at Lewes.
He said: "I'm 6ft and felt sure it was going to be a tight squeeze for me. But it was comfortable and there was plenty of room."
Sussex Police wanted to find out whether the car, already tested by other forces, would be suitable for getting through traffic-clogged parts of Sussex.
The vehicle's 600cc engine does 80 miles per gallon and can reach 70mph.
