In most recent version of vehicle software that I have (2017.32.6 ca 28227) I am having the problem that when I am about to pass an exit on the interstate (in the right lane, with autosteer activated), and there is not at least a dotted stripe on the right, the car will try to take the exit. (The navi system planned path is straight, not off the exit). A few times, I wrested control back, which scared my wife. (Now she tells me not to use autosteer at all). My current practice now is to hold the steering wheel firmly when approaching such an exit to force it to stay in lane; then autosteer chimes and turns off. This happens even when the striping on the left is quite visible. Is anyone else noticing this in the recent software versions? (I don't remember this happening up until recently). ...?
