We built our highways years ago, in many cases before the concept of an on-ramp was ever considered.
The typical way to enter a highway is to draw a bead on an approaching car, crank in some windage, and then floor it from the base of the chute. Normally you will have gotten up to speed, just after he's gone past, and you're in the lane. Everyone is happy, you didn't sin by causing an accident and slowing up the system.
Earlier today, there was a car just in front of me attempting this. She started, and I moved up behind. But then instead of moving out, she stopped dead while she looked and chatted with her girl friend on the cell. She seemed surprised when I was upset. I was surpried that I'd managed to not park two tons of accelerating Jeep in the middle of her trunk.
These are the big leagues honey, if you don't know how to play the game, GET THE HELL OFF MY ROAD !
This one happened to be young and female, but the thought applies universally. Our law requires a headset, she wasn't using one. This type of behavoir seems more prevelent on weekends. The weekday commuters are all pros with sharp skills. We charge and we brake and we speed and cut off and probably don't always use signals. But we all do it every day. And, especially in relation to the total miles driven, we actually do have a low accident rate.
The lame don't survive to foul it up a second time.
