I don't necessarily know if it's 8 times.... But NHTSA and IIHS state that you can not compare crash test data between weight classes. The only test that can be compared across the board is IIHS side impact (the one with the destructive barrier) - see below

Based on deaths rated from deadliest to least deadly....

Frontal - Most common single car accident including front offset impact (think tree or pole)
Side Impact
....
Rear Impact - Most common two car accident for commuters

Rollover is very uncommon (only 3% of all reported crashes)... But, they have a high fatality density. That is, in the unlikely event you get in a rollover - death is more likely.

I don't think that at anytime we are gonna get rid of big heavy vehicles, because some people want them for their luxuries, some need them for their hauling capabilities, and we're always gonna have freight. and lets face it... we're always gonna have stankin' rich people who can afford to drive big heavy gas guzzling vehicles! (truck, or no truck. we'll always have those Bugatti veyron drivers lol.)
I don't disagree... And I have no problems with people that use their vehicles for their purpose. My problem is when Jane has to keep up with the Joneses citing large=safety for her Dodge gonna go get a taco piece of farm equipment :/
