The left lane should not be considered the "fast" lane. It should be considered the passing lane. Once you pass a car you move over to the right. THis may require more lane changes but it it drives me crazy when people camp in the left lane for no reason.Here in CA, the left lane is intended as the fast lane. I get into the left lane and pace my car at the common speed of traffic plus 5. If the flow is about 70, then I set it to 75. The car slows and paces on the car in front of me. If they drop out, the car accelerates calmly to 75 and catches the next car and then paces back to the flow (70?) The DRCC is awesome for me. I think it was mentioned about downshifting and expect that it is only with the v6 with gear shifting. The Hybrid has CVT and doesn't "shift", but increases the rpm until speed is reached.
