from personal observation, blue dodge / Chrysler vans are the stupidest drivers on the road followed by honda odysees and then older ford rangers , but over all, pushing 90% of the time you get near one...jeeps attract the dumbest people to drive on a paved road - country wide!
Stupidest are those driving alone, windows closed, wearing a mask to protect themselves from the Kung Flu. (probably listening to NPR)
