Come on now, folks. How often do you
really have to stick your arm outside the window in the rain?

Wear and tear on the power windows? How many times in a normal day do you put the windows up and down? I think cars are built pretty good and we do not have to worry about wearing out the switches, etc.
Anyhow, I have a RAV 4 and have no problem opening the gates without lowering my window. The sensor card works perfectly from inside.
