Every driver is not born a racer! Don’t get me wrong, I am not against racers. There just many kinds of drivers that we observe everyday. There’s the cautious-careful driver, the cautious-careless, the responsible one, if there’s a good, then there’s a bad driver, and there’s also the worst drivers. I don’t say, that racers are the worst drivers. Worst driving means driving irresponsibly and recklessly.
Bad drivers may have in part something to blame for their behavior, says a neurologist at UC Irvine neuroscientists.
A particular gene variant is currently the subject of their study on driving behaviors. This particular variant limits the availability of a protein called brain-derived neurotrophic factor (BDNF) during activity. When a person is engaged in a particular task, which in this case is driving, BDNF is secreted in the brain area connected with that activity to help the body respond.
A simulated driving test for two days was given to 29 people, 22 without the variant and 7 with the gene variant. Results showed that the 7 subjects with that particular variant did worse than those 22 other.
