* unrestricted highway speeds
* a structural deficiency on the model S which causes the A-arms to break at high speeds
* no mandatory manufacturer service but mandatory car safety inspections
Without unrestricted highway speeds the a-arms are unlikely to break. With mandatory manufacturer service intervals broken A-arms would be spotted ahead of the car safety inspection (TUeV). Likely without that a-arm deficiency this wouldn't happen either. So I would not expect the model 3 to show the same statistics.
If this topic is of interest to you, google for "Model S Querlenker" on the German internet and you will find many affected folks. Yet that particular issue is not anywhere else as widespread because people just drive slower.
