My car is due in any day now. I took an "extended" test drive today. I took it into stop and go traffic, up and down hills and out on the highway. The "lag" was noticeable only because I wasn't used to how it shifts. By the time I brought the car back to the dealer, I had the shifting down pat. The only thing that really did bother me was the lack of visibility while backing up. That's a bigger problem than the shifting
