Honestly, I've gotten used to just using the manual wipe button until there is enough precipitation to justify having the normal slower constant wipe speed engaged without chatter/squeaking. I do try to use the auto wipers, and even try to "train" them (even though I know they likely aren't programmed to be trained), but they only work decent in very few certain types of precipitation. I haven't disabled auto wipers yet, but I probably should, because then I could use the intermittent settings sometimes even though I'd probably still use the manual wipe button due to the limited number of options there. The most annoying thing about this is that I had awesome auto wipers in a 1998 Buick so this was already a solved problem for any company other than Tesla who just insists on Tesla-ing.
