My last Toyota was a 2017 Prius Prime: I traded a 2017 Prius Prime for a 2019 Tesla Model 3 in large part because of the control laws. This video makes me angry, again. Inside the pack: Bob Wilson
lane alert instead of lane keeping - it would 'nudge' the car back toward the center but lacked basic PID logic to stay there. After the third "nudge' it was headed to the ditch. too easily enabled ICE - when I want 'EV only', that is what I want, not unexpected ICE operation. Bob Wilson
I've worked with computers long enough to know that they do what you tell it to do; NOT what you want it to do.... I don't use and turn-OFF my lane keep assist, Don't need a nanny or back seat driver trying to tell me what to do. If you have that turned-on, you better be using your turn signals; otherwise it'll always nudge you anytime you get close or go over a line. I've never had my gen4 enable ICE when it didn't have to - in fact I force the ICE ON when I'm up to speed on the highway; because it's more efficient beyond 50+mph. Switch back to EV mode when I'm on city surface streets again.
In my 2024 RAV4 Prime, LKA (Lane Keeping Assist) feels too intrusive, so was quickly turned off. I didn't use it long enough to determine if it was trustworthy. "EV-only" has worked worked perfectly, apart from the one coldest ski morning in Colorado where "Start" went instantly to HV mode, skipping EV.
