I'm sure this has been posted before, but I just discovered after almost a year of ownership of my RDX that the rear wiper does a couple of swipes with the the front wipers are on and you put the RDX in reverse. Took me by surprise as I thought I had put the rear wiper on by mistake, so I fumbled to turn it off. Silly me.

 

Well, here is another one. Front wiper slows down when the car comes to stop and resumes its set speed once the car moves.

 

here's another one while intermediate is on, once you release brake pedal your wiper will swipe

 

Ane heres a really cool one! In reverse both the SH-AWD display and speedometer work!! Found this out this past winter backing up in some snow.
