why？The other day I put on the navigation. It was supposed

to change lane to the left to make a left turn. However, FSD reacted too slowly, I had to take over almost at the intersection of the road, slowing down almost to a stop for the left lane car to by pass before switching the lane. The other time, there was a contruction block on the left lane but FSD did not detect and still made the lane change. I had to take over again. Incidents like this does not bode well for the robotaxi.
