Little worried about that
hot exhaust

That was a kit bike, and I suspect today's regulations would not allow
for a kit to be sold using a gasoline engine.
============================

 Our agency, the National Highway Traffic Safety Administration
(NHTSA), is authorized by the National Traffi c and Motor Vehicle
Safety Act (the Safety Act) to issue safety standards applicable to
new "motor vehicles" and new items of "motor vehicle equipment." The
Safety Act defines a motor vehicle as:

any vehicle driven or drawn by mechanical power manufactured primarily
for use on the public streets, roads, and highways, except any vehicle
operated exclusively on a rail or rails.
...
...
NHTSA has authority to regulate the manufacture and sale of motor
vehicles and items of motor vehicle equipment. Thus, the Safety Act
prohibits any person from manufacturing, importing, or selling any new
vehicle that does not comply with all applicable safety standards. See
15 U.S.C. 1397(a)(1)(A). The Safety Act also required Cushman to
certify that each of its on road three-wheeled vehicles conformed to
all applicable safety standards. See 15 U.S.C. 1403. Additionally, the
Safety Act requires Cus hman to recall and repair those vehicles if
either Cushman or this agency determine that the vehicles contain a
defect related to motor vehicle safety. See 15 U.S.C. 1411-1419. It is
the individual State, Massachusetts in this case, that has authority
to regulate the operation and use of motor vehicles in that State.
