That little rolling critter brought back memories.... back... waaaaaay back....
California, high school... 1973. Friend had a Honda 600. Two-cylinder engine. Not a motorcycle engine, made specifically for the car. Forget if it was a four or five speed but it got 40 mpg and more.
Itty bitty thing with 12-inch wheels if I recall correctly.
So small he could and would drive it down the sidewalk, a normal-sized sidewalk and have all wheels on the concrete.
With gas at 29-32 cents per gallon we could cruise forever and have plenty left over for illicit substances.
The pic is representative but my friend's itty bitty rolling device looked like new.
