This falls under a broad category of quibbles I've had with AP on the highway that's like.. think a step ahead or second-order decisions making.
Another example of this I find annoying is when traffic has slowed considerably off in the distance but still very clearly visible and coming up quickly. The car will basically cruise along at speed (or even speed up if it was below set speed and a space opened up).. right until it needs to hard brake.
Similarly in some stop&go traffic situations, as car ahead creeps forward it may let a larger than normal gap grow.. and then jerk forward then hard brake. I've seen this happen far too often. Rather than sort of coasting slowly up to speed and then back down..
Feels like the software has a binary black&white brain, and only decides to GO or STOP, without a lot of nuance to how hard to GO or how hard to STOP.
There's a certain lack of smoothness. If your Uber driver did this you wouldn't rate them well.
Reminds me of old yellow cab riding in NYC when you know the guy is on his 6th 12 hour shift of the week...
