I spent over six years commuting ~120 miles/day (round trip) to the capital region from the north.
I think the worst drivers are from Vermont because they absolutely REFUSE to use the right lane. They get into the middle lane, pass NO ONE and will not budge.
NJ drivers are aggressive, but they follow the rules of the road. Same with drivers from downstate NY/NYC.
PA drivers are aggressive, but also irresponsible and selfish, I.e. passing on the right.
And anyone driving an Audi, regardless of state, drives like an #######. 100% of them.
