I always left it on on the road and never found it very obtrusive in the 182, usually at the head of the bunch too if out with 172 / 182 owners on a meet so never felt the need to turn it off.
Turn mine off everytime i get in the car, its the first thing i do, just as important as wearing my seatbelt.
Hate all that electronic wizardry - drive it properly.
Hmm bit of a hero??
I'd rather that little bit extra safety when driving on wet back roads at night etc..if the wheels spin up it might actually save you and or your passengers life as it may have stopped you going through the fence, down that grass verge onto the railway line or the likes.
Lol easy now Edinburgh..
