On the drive in to work this morning I had a terrifying incident that almost caused a major accident on a busy Atlanta interstate. I was driving in one of the left lanes and noticed a car behind me clearly wanting to go faster than I was traveling. The next lane over was open and there was a tractor trailer two lanes over. I signaled to make the lane change and the car started to move into the right lane. As I moved over, the car behind me began to accelerate to pass me. Suddenly Autopilot mistakenly thought the semi-truck two lanes over was in the lane that I was moving into (showing it in red) and the car began moving back into my original lane. I jerked the wheel to the right and the car that was passing me slammed on his brakes, angrily honking his horn, flashing his lights, and giving me both fingers as he sped by. It was a seriously close call. I've noticed before, particularly with large trucks, that the visualization thinks the truck is one lane over when it is actually two lanes over. Not sure why this occurs.
