Oh please. What you are talking about is nothing. I drive in Chicago all the time. Check my profile to see what town I live in.
There is a merge I go though every day. It is on 290 west just before it ends. 290 and 90 cross right at Algonquin road. The exit ramp from 90 goes into westbound 290, then turns into the off ramp for algonquin. there is about 140-200 yards to merge for 90 traffic to merge onto 290. I have to get off there at algonquin, so I have to merge with the traffic from 90 and 290 at once.
The people who are usually driving it when I am know exactly what they are doing though. If you time it right (which you have to do) I (going about 75 and decelerating) merge with the traffic coming up the ramp (40ish and accelerating). You look at the other driver, and if you make eye contact for that fleeting instant (maybe 50' of eye contact area, for a 1/2 second or so) then you can instantly tell that the other knows exactly what to do.
we (coming up on the merge) time it so the other driver is about 4 car lengths in front of the 290 car, with the distance rapidly closing. then, right as the solid white line breaks, you switch lanes. Then, because of the speeds involved, the car that was on 290 actually passes the car that just merged onto 290 from 90 while decelerating for the turn on the exit ramp. Just as the exiting vehicle hits the first bit of the turn on the exit ramp (a downholl sharp one) the car on 290 passes the exting vehicle.
Quite frankly, it is astounding to watch 3 or 4 cars do this all at once on that ramp. Is is the only place in the Chicagoland area that I know of where drivers are actually working together.
