Weaker Construction
Risk to Other Road Users
Implications for National Insurance Costs
Poor Visibility and Backover Deaths
Wide Bodies in Narrow Lanes
Invulnerability Psychology
Poor Fuel Economy
Increased Traffic Due to Space Between Vehicles
More Pollution
Just a few comments:
In 2003 and 2004 in the U.S., passenger cars were involved in 1.65 and 1.58 fatal crashes per 100M miles respectively, compared to 2.14 and 2.05, nearly 30% more, for light trucks (SUVs pick-ups and vans). In 2004, light trucks were involved in fatal two-vehicle crashes with passenger cars at nearly 3 times the rate as passenger cars.
Of the vehicles that received a perfect 0-metre blind spot rating, 11 out of 42 (26%) were SUVs and 8 out of 163 (5%)
According to G. C. Rapaille, a psychological consultant to automakers, many consumers feel safer in SUVs simply because their ride height makes "[their passengers] higher and dominate and look down. U.S. potential SUV buyers will give up an extra 30 ft (9.1 m) of braking distance because they believe they are helpless to avoid a tractor-trailer hit on any vehicle.
The IIHS report states, "Pound for pound across vehicle types, cars almost always have lower death rates than pickups or SUVs." In 2004, the National Highway Traffic Safety Administration released results of a study that indicated that drivers of SUVs were 11% more likely to die in an accident than people in cars.
The CAFE requirement for light trucks is an average of 20.7 mpg-US, versus 27.5 mpg-US for passenger cars.
