It's not the size of the car, stupid!
If you google this topic, you will find the best correlation is not between injury and car size. The cost of car has the best inverse relationship to the numbers of death or injury on drivers' side. I did it some time ago and there has been scientific study done on the subject - you just need to find for yourself. All the 3 toylish cars cited here are cheap cars, do you think that's just a coincidence? The F1 race cars are small and light, and you think your gas guzzling SUV is safer than them? Gi'me a break already.
