There should be a tax applied to excessively large consumer vehicles. They have an outsized affect on the roads, on the safety of others, and cause stupid things like not being able to see past them when they are in front of you.
They should also pay much more for insurance, since they, again, will consume an outsized portion of it, compared to others not driving a penis replacement.
For pedestrians, I suspect it's no different. Whether you're hit by a Kia Soul or one of these Canyoneros, you're still quite likely to die, assuming the vehicle is going faster than 5mph.
