Earlier by Steve Sailer: Are Blacks Really 3.5x Worse Drivers Than Whites?
Steve is rightly suspicious of the statistics in the report below (small sample size, made smaller by dividing by race) but blacks are worse drivers than whites in the sense that they're more likely to commit traffic violations.
Liberals suspect that police are more likely to stop blacks for traffic violations because they know that blacks are more likely to be fugitives from justice, more likely to have illegal drugs, more likely to have illegal guns, and more likely to have kidnap/murder victims in their trunks. (Pictured right, alleged serial killer Stuart Weldon—three bodies have been found on his property, and a live woman in his car thanked police for saving her life.)
But of course the idea that police disproportionately stop blacks for speeding because they know about the differential crime rate is based on the idea that the group that commits all that drug crime, gun crime, kidnapping, raping, murdering, etc. only violates the speed laws exactly as much as whites do.
Eighteen years ago, I pointed out that that's not true, in an article called Heather Mac Donald Debunks Racial Profiling
[A] survey by the State of New Jersey on the relationship between race and speeding produced a very interesting statistic: black drivers speed twice as much as white drivers!
Heather Mac Donald wrote up a study in New Jersey, where there's a lot of black crime, and thus a lot of profiling complaints:
According to the study commissioned by the New Jersey attorney general and leaked first to the New York Times and then to the Web, blacks make up 16 percent of the drivers on the turnpike, and 25 percent of the speeders in the 65-mile-per-hour zones, where profiling complaints are most common. (The study counted only those going more than 15 miles per hour over the speed limit as speeders.) Black drivers speed twice as much as white drivers, and speed at reckless levels even more. Blacks are actually stopped less than their speeding behavior would predict—they are 23 percent of those stopped.

On the subject of speeding "at reckless levels" see
For the popular black argument against racial profiling, see "Chamillionaire"'s classic "Ridin'" AKA "Ridin' Dirty" [Lyrics]:
If you either read the lyrics or watch the video, you'll see that the character (not necessarily the rappper) is a dangerous criminal who should be stopped by the police.
But aside from his "pistola" "Glock" "drinkin' and smokin'", "blunt up in my right hand 40-ounce in my lap" and so on in the lyrics, he's also speeding and violating the seatbelt laws, so in stopping him, the police are applying the same laws they do to whites...which is racist.
