How is a common sense test made? Some drivers are lacking in that skill. The exams don't seem to be able to weed out the baddies. Then there are the stunting drivers speeding and racing around. That's now a charge in Canada called, "Stunting." It carries a serious penalty and confiscation of the vehicle for a period of time that is substantial. For some people charges are the only answer and if that is caused by a lack of common sense then so be it I think. It has been made apparent to me that for example German drivers have a much more comprehensive drivers test arrangement in comparison to Canadian standards. The same goes for using the cel tel when operating a motor vehicle; that should carry a serious punishment as it is worse in some ways to impaired driving in that the driver is not even looking at the road when operating the cel tel. When operating a motor vehicle I consider that a privilege and a serious operation and I drive accordingly. I'm not sure repeating a driver's examination is the answer as I've seen some low intelligence people that are great natural drivers and vice versa.If it's incompetence, it may be more efficient to detect them by making everyone re-take the driving exam every 5-10 years. That won't detect the alcoholics, but I don't think it would be a bad idea to also require a basic medical exam to get a drivers license.
