Legroom is at a premium in this car.

Check out this custom-built vehicle, which Guinness has named the world’s smallest car.

Austin Coulson is the mad man behind the car, which measures 25 inches high, slightly over two feet long and a hair more than four feet long. And like any car you’d see trolling the roads, it has turn signals, a horn and windshield wipers, which seems slightly extraneous given there is no roof.

At a mere 45 miles per gallon, the car is also not ideal for going on that cross-country road trip you’re planning, either.

And judging by the size of it, we also recommend you avoid using it for your carpool.
