Absolutely, an essential part of driving is predicting how the state of the world will change in the future - and the behaviour of a motorcycle is vastly different from the behaviour of a stroller.

In this case it doesn't matter, because there's a car in front anyway.

I don't know how much the system can ignore or mislabel people and still drive safely, but right now it's not really safe and it's not necessary to have the car drive while improving object recognition.

Presumably strollers and motorcycles have very different behaviors to predict.

generally speaking the cloud of future position where a person or a bike can be is wildly different
