Most of the time I got 1st to 3rd, 5th and 6th if I am fast enough or if the wheels are turning I go 2nd to 4th and then 6th. My brain hates traffic not because I have to shift often but because I hate sitting in traffic. I honestly never found my self hating the fact that I shift.
Driving an automatic on the other hand irks me because I can't predict (the same way I do with a manual) what dose of acceleration I am getting. It just doesn't feel right. So in the end I don't care if there is traffic or not.
