Just get used to different vehicles.
When I spent 99% of my driving time driving a CMV, I experienced the same thing when I was home and drove smaller vehciles. I'd drive my pickup like it was a 65 foot long combination vehicle until I got my brain back into "4 wheeler" mode. Didn't operate unsafely at all, just did silly things like take turns wider than I needed to and would reach for a shifter that wasn't there. Oh, also felt like my ass was dragging on the pavement. In the wife's car it was as if I was going down the highway sitting on a skateboard.
Simple psychological conditioning. Brain gets accustomed to a particular environment and when that environment changes it takes a few minutes to readjust. Or, in the case of my wife's car I just plain hate driving it because the visibility out of the windows is horrible. Dodge Intrepids suck.
I ride 652ccs of slug.
