It's simple, Prius drivers
It's simple, Prius drivers are smarter. I would agree with that. Taking my own personal pole of those I know with each type of vehicle, and the habits of watching others on the road, SUV drivers are by and far concerned about getting to their destination asap (and you're in their way)..., while a Prius driver is doing their best to drive slower and conserve even more gas (yes, there is a discrepancy between MPG between different styles of driving the Prius).
