Too Aggressive Pulling in Passing Lane

This site may earn commission on affiliate links.
When using FSD, I find that quite often the car will signal to pull into the passing lane while a car is approaching in the passing lane at a higher speed than I am going. Thus if I do let it move to the passing lane I will have someone right on my tail.

Normal behavior - it's been going on like that for at least a year... Just wait until your X attempted to make that lane change - and the person in the target lane speeds up to try a block (or uses the merging lane to speed around you)...
 
I suspect this is always going to be a bit of an issue. There's no rear radar, so AP has to estimate distance and velocity with only the rear fish eye camera and 1 side repeater. Then it needs to make the decision to lane change, confirm your attention, potentially get confirmation to change lanes and execute. Probably not a problem for most of the time, but vehicles overtaking at a high rate of speed are like are going to be hard to predict.
