Tonight, as I was driving back, I had VERY little condensation on the car. I mean very very little! So little that it was not visiible to human eyes. And yet TACC got confused. Said cruise not available because front camera is blocked. I pulled over in a parking lot, gave it one wipe with a tissue, and it started to work again. I really wonder how this will work in winter or rain. I really wish they give us the non-tacc option cruise (constant speed) option in the next firmware update. Also, how much do you trust TACC to not rear end anyone? I've been trusting it, but tonight (after I wiped the camera with a tissue), the car seemed to speed up rapidly towards a car in front of me. I hit the brakes manually, I wonder if TACC would have figured it out? I think TACC gets confused on up/down slopes a lot. Also, I wish TACC could see red/green lights. This is also my first car with TACC, am I expecting too much here?
