It may not the case in US and Canada, but it will be the case in China.
Are you asking for a friend/relative who lives in China? If so, and I could be pulling this out of my a$$, I don't know if I'd trust AP just yet over there. The drivers mindset is different, lot's of random pedestrians and scooters, and depending on where you're at, the roads may not be drawn up clear enough for AP to track. The other thing is that the threshold for being "cut off" is a lot lower too, so the cars are operating from within inches of each other.
