we saw an aluminum ladder in the middle of one of the lanes on the interstate.
I'm in no way saying that there can't be "stuff" on the highway that could/would cause all levels of problems .... such things as you saw most certainly are out there .... if a person driving an Elio was to hit a ladder like you saw, it could be bad but with 3 wheels would hopefully not be in the same class as hitting it with a 2 wheeler
