+1 I make my living (teaching and administration) at a very large university. Common sense -- even common decency -- is not a given among the 'educated classes' or 'higher socio-economic groups'. Far, far from it.

Further, my experience suggests that poor/aggressive/dangerous driving behaviour correlates (if it correlates with anything specific) with 'luxury class vehicles' (car or SUV/pick-up) just as readily as it does with other vehicles.

Quite a bit of arrogance in some of the responses here.
