I actually meant turn sign within traffic signals. Not the turn signal of a vehicle in front.Thanks for updating! I have one more suggestion. In their autonomy day, Tesla (Karpathy) said that Tesla's current strategy is not to explicitly recognize turn signals, but instead to holistically recognize "intent to turn". This is because sometimes people don't use the turn signal and sometimes people leave it on. So far they have implemented this for "cut-ins", or cars that are about to change into your Lane in front of you. So maybe it makes sense to replace turn signal recognition with "intent to change lanes" and "intent to turn". The first has already been implemented on ap2.
In fact, maybe there should be an entire section on "predict other drivers' behavior". This could include the above, plus the likelihood that stopped traffic at a crossroads will pull out in front of you (including 4-way stop signs), and also the intent to "let you in" on a lane change or "let you go first" on a narrow 2-way road or bridge that can only accommodate 1 car. I'm sure there are more examples that could be added.
I think the predict other driver's behavior is a sub-feature under each of the features. So, it is kind of platform level feature. You need to be able to predict how the car that is coming in the opposite direction will behave before you can take a left turn, for eg. Or whether the car parked behind you is also trying to come out of the parking slot to be able to safely pull out of the parking.
So, just as they had to predict whether another car is cutting in to be able to do safe lane switches, or each of the features, they have to figure out the various obstructions that can happen on the way and be able to predict those obstructions.
