Why? It just seems to be frustrating to you. There's no downside to avoiding unnecessary slowdowns, and plenty of upside (reduction of collision risk, reduction in trip time, smoother ride, better efficiency). No information is typically lost because honestly it's pretty difficult to be skilled enough with the accelerator to avoid ANY undesired behavior. Certainly there's no information lost for Tesla. And you can hit report (FWIW) even if there wasn't a slowdown, if you think it would have, or any aspect of the behavior was unnatural. It doesn't have to be awful.
