Great graphic, Mary. Now come up with one that explains how the on ramp enables you to get up to freeway speeds BEFORE you join the freeway. I am so weary of being forced to enter a freeway at 40 mph cuz the idiot entering ahead of me thinks, mistakenly, it is safer to to merge with freeway traffic while going 20 mph slower than the traffic. mad
