Yes, I think it's safe to say that racism is part of it. But as a poor white person, I ask why nobody has yet (as far as I am aware) suggested that classism might also be a component?

It's often really hard to discern the color of a driver at night, especially from a distance and without a direct view, but it's considerably easier to estimate the driver's class position from simple observation of the car. For example, perhaps those who drive clunkers are both disproportionately likely to both be of color and to be stopped.

Driving While Black exists, why not consider and address Driving While Poor? Because it's harder to quantify, or because there is no Poor constituency of consequence?

Terry has an interesting point...I have seen numerous traffic violations near a police officer that did not result in being stopped. The vehicles:upper end or luxury. The drivers:White or Asian....coincidence? The economic factor seems to be a component however
