A Gene for Bad Driving?

Perhaps this explains what one police officer I know calls "DWO" - Driving While Oriental:

Bad drivers may in part have their genes to blame, suggests a new study by UC Irvine neuroscientists.

People with a particular gene variant performed more than 20 percent worse on a driving test than people without it - and a follow-up test a few days later yielded similar results. About 30 percent of Americans have the variant.

"These people make more errors from the get-go, and they forget more of what they learned after time away," said Dr. Steven Cramer, neurology associate professor and senior author of the study published recently in the journal Cerebral Cortex.

The article doesn't suggest it, but I wonder if this gene variant could be a dominant trait in Asians? It would be easy to think that driving around Orange County.
