18.6.1 was acting really bad tonight. I've had 18.6.1 since the day it was first released and have gone on several road trips of 50+ miles with it and used AP almost 90+% of the time. 18.6.1 has been really solid with only the most glaring known AP issues having to be dealt with. Went on another road trip tonight and engaged AP and right away I noticed it hugging the right line. Way too close! Then it started swerving in the lane like it had know idea where it was. Even had a lane change abort half way and the car jerked back to the original lane. I tried engaging AP several time more at different points along the trip and every time AP would freak out at some point. So I ended up driving myself the whole way.
I've had my MS since Aug, 2017 and have gone through many software updates and I've never had AP act like this since I got the car. Even with all those earlier versions. Also, I've taken other trips with the exact same software version and it worked really well. Can't figure out why all of a sudden it would stop working well. I did have the MCU reboot the other day for the first time ever.
Was hoping to get 18.10.4 today before the trip but haven't got it yet. Thinking of doing a complete reboot of everything before trying AP again.
Suggestions?
