These things are NOT street legal.
The problem is when people ride them like they ARE.
My one anecdotal exposure.......... Last November I had a call where some I-D-I-O-T was riding one of these down the side of US1.
He proceeded to get smacked by a car that did not see him. When I got to him he had a pool of blood the size of a dinner plate next to his head.
Put him on a helicopter, got him to a trauma center & he died 9 days later.
When you mix TOYS and CARS, the moron riding the TOY LOSES!!!!
If you want one, ride it up & down the driveway, or an empty parking lot, or an approved race course.
Not
The
Road.
OK, Tirade over.............................
