The only significant differences between AirTags and other devices are the fact that the victim’s phone might be used to transmit their own location and the widespread availability and marketing of AirPods compared to other devices. Apple can’t really do much about the latter (other than discontinuing them), but it seems like they could partially address the former by having each phone only transmit the location of non-owned AirTags a single time. This might not work if the victim’s car if in heavy traffic where phones in other cars can transmit the location, but it could at least help in cases where a single car is driving home alone.
