My take is as long as it passes a state safety inspection and ANYBODY can get in and dive it 100 miles then it's a street car. That being said my car wouldn't meet my standard criteria
I've had to teach people how to shift a V-gate with face-plate non-syncronized gears My heater valve started leaking on the gas pedal so out went the heater til I get the valve fixed.

I still think it's a street car that runs tens on pump gas
