Anyone ever consider how unsafe cars are to other people/living things?
Seriously, the risks to life and limb (not just your own) go up rather steeply just by getting in a vehicle.
Who do you think is killing all those pedestrians and bicyclists? People who feel safe in their cages for the most part.
Motorcycles are a bit of an exception, as the stats include a population with a high percentage of "risk takers" and more affordable high performance machines. But still, the predominating risk for motorcycles is stupid cagers.
