Maybe they could come out with tiny wipers for the sensors. ;o). I need to see Owl come out with that. @Jean Mercier could figure out how to wire them up.The only issue I have had is the two rear parking sensors sticking on when it rains. Spraying WD40 into sensors clears them. It repels the water that causes the sensors to play up. Until the next time water gets in them. I have seen several others report this issue.
