I find that when I have been riding (only riding) for a long enough time, that when I get into an enclosed vehicle, (car/truck) that I have almost no sensation of movement or speed. I assume that this is due to the absence of wind pressure. But I really have to watch speeding, it is way too easy to get going too fast until I get used to being in a car again.

and yes, the solution to this is obvious
