Problem is rain sensors have never been perfect either. Not saying that the Tesla system is currently better, there are enough complaints out there to tell me that it's not consistent and there are issues. Like everything else Tesla have not settled for 'good enough' just because everyone else does and are trying to find a better way to do things.Im suprised there isnt a third party add on by now. Shirley if its that simple and cheap someone would be selling millions of them by now?
I'm not sold yet that this particular experiment will work, though I'm encouraged in my case that my wipers have been overall very good, better than rain sensors in varying rain with the only issue I really have being the occasional dry wipe.
I think they will have to improve it considerably in respect to the consistency or they may finally settle on adding a rain sensor and just putting up with 'good enough'
