Funny enough, I also drove my Model 3 yesterday and had to forcibly override the autosteer when it tried to swerve into a merging onramp on the left (since the white lane marker was suddenly ten feet further left) instead of just continuing straight ahead, and this is a pretty regular occurrence that I've come to anticipate. This system may work someday but today it's still dumb as rocks.
