Apparently, playing racing games will make you a bad driver. Most of the report here is common sense, but the thing I find troubling is the part where it states that drivers who play games are likely to have slower reaction times.
This goes against virtually every other study in the field (there are some particularly convincing reports on the benefits of gaming in boosting the skill of surgeons). I wonder if the study group used one of the Need For Speed games? They bear about as much resemblance to driving as they do to clay pigeon shooting.
