Things are a lot different now than 30 or 40 years ago.

First, video and internet wasn't available when I was a kid, so there was no chance of someone posting an inflammatory video. Stupid things tended to be kept contained rather than broadcast.

Second, the drugs and booze aspect that goes hand in hand with the ricer crowd played a much, much smaller role in the musclecar scene.

Third, there were far fewer people driving around the streets back then.

Fourth, public sentiment against driving while stupid was much less back then. People as a whole just didn't care as much. society was far less litigious.
