I'm 6'4" and no problem. Oooo! Look at that wooden steering wheel! The craftsmanship:
The story is some guy from Utah (Steve Hall) wanted to build a vintage-like car without the hassles of vintage cars, but to do it with 4 wheels in the modern era requires so many monies because regulations. But with 3, you get to classify it as a motorcycle (autocycle) and the regulations let you get by without airbags and most of the other stuff, so the price tag can be reasonable, the look amazing, and the weight light.
You still have to have a yellow reflector in the front and red one in the back. Vanderhall put them in the center of the wheels:
You don't need a motorcycle license or even a helmet to drive it. But you can go like a bat out of Hell: 0-60 in 4.5 seconds, great handling in part because of its front-wheel drive, and an awesome throaty sound without being obnoxious.
