Which medical specialist speeds? And which is likely to own a luxury car?

Police man a speed trap in this filepic. A study finds that psychiatrists are the most likely to speed, of all the medical specialists.

Psychiatrists are most likely to be fined for extreme speeding, while cardiologists are most likely to drive luxury cars, according to an American study of physician driving behaviours in the Christmas issue of The BMJ.

But the theory that certain specialities may be treated more leniently by police officers than others is not borne out by the results.
