Real simple answer is what they do in some parts of Illinois.......they have a timed stop light at the bottom of the on ramps. Eliminates all the merging problems.
I personally think the semi's are the WORST mergers. They just put it to the floor and if you are in the way on the interstate when they enter from the ramp, oh well. :R
I don't care if they 'move' America, I think we need to start making noise and get these darn cops to start enforcing highway rules when it comes to semi's. That and for gawds sake stop them from pouring their urine in the rest area parking lots. JMOT rant! :B
