I hadn't spotted this, but you're right. It's actually slightly worse - to justify this, the author links to another article titled "Fatal Pedestrian Crashes Increasingly Involve SUVs, Study Finds".

I say this is off because an increase in proportion of SUV involvement is primarily an indictator of popularity of SUVs, rather than anything about SUVs being more deadly.

I happen to believe, fairly uncontroversially, I think, that SUVs are far more deadly than a regular car, hitting adults in the chest instead of the legs, and children in the head instead of the chest, but I also think poor journalism is pretty dangerous, and worth investigating.
