It took me a couple of weeks before I had enough confidence to use it pretty much all the time around town. So when I show newbies, I make sure we're in an area with no 'challenges.' Bob Wilson
Be aware that the LKA in the latest release is not Autosteer (autopilot) If Autopilot is ON you will never see it ping-pong. If Autopilot is OFF and you have the LKA(activated to Assist) in settings, it will ping-pong. It is not intended to be active autosteer. LKA is a Safety feature added to the Fleet regardless of whether you purchased AP/FSD. I have EAP/FSD in my Model 3 Performance. It does Ping pong in LKA mode. It is just there to prevent crossing the lane line.
