Wait, what do you mean black people are more likely to be pulled over, not because they're black, but because they're more likely to be young and hence more likely to speed? Which stat are you using, young black drivers as a proportion of all black drivers? Youn black drivers as a proportion of all drivers? And assuming we can assume all young drivers, regardless of race, are more likely to speed (unless you say otherwise), are the patterns of being pulled over amongst young black drivers similar to the patterns for young white/other race drivers?
