I've got a Mazda 3 and I don't worry about SUVs or trucks running over me. Drive sober and watch the road, don't use your phone. Do this and you reduce your risk of an accident by something absurd like 1000x.

The reason people love massive vehicles is because they're shitty drivers, they know they're shitty drivers, and they have no intention of changing. They want to text while driving and they want it to be the vehicle's responsibility to keep them alive when they go off the road or get run over by a train, or drift into the opposing lane. Keep your eyes peeled for these morons, keep your head on a swivel. If you're attentive you're already in the 90% percentile. Paying attention is better safety than even a seat belt.

I love minding my own business and not having to worry about driving through narrow roads, etc. People definitely drive SUVs so they can try not to care about other people.
