I have the same immediate weird feeling when driving a car for the first time after riding the bicycle to work for many consecutive days, especially the increased annoyance at traffic lights.

The sensation that going 25 mph in the car is too fast for conditions goes away after a little driving, when my expectations get re-set to being a car driver again.

The annoyance with traffic lights seems to linger. Part of that I think is because when I am riding, a red traffic light may delay me slightly in reaching the destination, but commuting is not a race, and the red light can be a chance to get a short breather, perhaps a drink of water if I have time, and let the legs rest a bit. In a car, a red light means just more delay and burnt expensive poisonous fuel chemicals, there is no resting benefit. I haven't driven enough in the car since I started bicycle commuting to see if that sensation gets re-set to 'normal' for car driving after a while. Also, frustration with idling at traffic lights is one of the 20 or so great reasons why I like biking to work so much better than driving anyways, so the pre-existing annoyance with red lights is probably amplified now that I know transportation can be done better than by car.
