Since there don't seem to be any reports of rollovers of '17 RAVs on this forum it is likely that one would need to drive like an idiot to roll one, unless they were broadsided by something like an 18-wheeler . . . .
Death rates don't reveal anything about a model's rollover frequency, just that its less survivable in that model. There is surprisingly little hard data on the frequency of rollovers per model. Most all significant data comes from accidents involving death. But in accidents involving either injury or death, SUVs have the highest incidence by far.
