Bad Driving is Genetic

The next time you see a motorist obliviously straddling two lanes, don't blame bad driving, but genetics. In a recent study discovered by Steven Cramer from Cerebral Cortex. He found that people with a certain gene variant performed more than 30 percent worse on a driving test than people without it.
This study might also help explain why there are so many bad drivers on U.S. highways: about 30 percent of Americans have the variant. Ordinarily, when a person does a task, a protein called BDNF is secreted to the area that is related to the activity being done. People who are bad at driving, BDNF secretion is limited. The protein helps facilitate communication among brain cells and helps retain memory.

"These people make more errors from the get-go, and they forget more of what they learned after time away," Cramer said in a statement.

They recruited 29 people for a test. They were to drive 15 laps on a simulated coarse. 7 of the 29 people had the variant.
