phantom shiftosis syndrome 

Reaching for the shift lever in the wrong place when driving somebody else's car

My car's a '99 Camry (shifter on the floor between the front seats). My wife's car is an '02 Odyssey (shifter on the steering column). Any time we use each others' cars, we come down with a case of phantom shiftosis syndrome.
