Probably you're correct, but..when overall decline in a given market happens, those most resilient pay attention to details that help overcome objections. Parking sensors were an example, particularly when many others do.It is definitely an annoyance to most people (like lack of care for non FSD AP in Europe, speed sign recognition a big mess for a long time) but I think the decline is more due to macro/people reluctant to commit to any large spending
The Tesla ones, with displays of actual distances in tiny increments, were a huge advantage in narrow urban settings, especially ones prohibited to non-EV traffic. Were I buying in Europe they would be a deal-breaker for me, not for parking per se but for tight navigation.
Similarly any market should have really excellent navigation support for various alerts, with speed limits being crucial. FWIW that would be a deal breaker for me were I in Europe just because I drive often in Germany. Leaving a limit-free Autobahn for a limited area has cost me before, and does so for others also. I rather suspect the Netherlands, for example, is subsidized heavily be travelers from, say, Hamburg. My last one cost me €2200. That would have paid for decent speed limit recognition!
Both of these are small. Tesla should take better recognition of human driving needs. After all it's human drivers who buy most cars.
