This may be the cyclist's worst enemy (after the City Bus)

On the occasion of nearly getting clipped for the third time in two days, I pose this riddle to you, Constant Reader:

Do you have to be dumb to drive a Pontiac Grand Am? Or does driving a Pontiac Grand Am make you dumb?

In other words, which came first: the dumb or the Grand Am?

Incidentally, I have heard from a number of reliable sources that more than any other make or model, the Grand Am is universally known to be crashed and dented and blown up and otherwise maltreated at the hands of the world's worst drivers. True?

I see no evidence of this urban myth at Wikipedia, but I did notice this highly relevant note:

In Popular Culture: A silver 1999 Grand Am SE2 appeared in
the 1998 movie Lethal Weapon 4.
