In a low car (such as my mothers MX-5), all you can see through the back window of and SUV is the roof! this is a problem when you mare watching traffic further up the road through the windows! You also cannot see low cars on front of them!
My car stops better than any modern SUV and it is seven years old! I would never buy an SUV (many of which are only 2WD anyway) and I am of the opinion they they should not be road legal!
Compared to any car of the same era and price range, an SUV will lose in handling tests.
Yes, sedans and such can roll but normally they will slide first, this gives you a chance to bring them back under control.
As a cyclist, I have been ht by a sedan and all I broke was my arm, Somebody who was hit at lower speed by an SUV got knocked under the car, broke three ribs and had his leg crushed by a wheel! You are much safer landing on the bonnet of the car than going underneath! The same thing happens with pedestrians as happens with cyclists.
Another thing that should be banned is a bull bar, they are quite dangerous and will knnock the pedestrian under the vehicle
