That is interesting from a mass-implementation standpoint. I wonder how many Tesla vehicles working right next to each other would squash AM reception for a given radius around the group of cars with current EM emissions.
In theory, they could form some sort of phased array beamforming to fuck one guy in particular, but ignoring that sort of targeted malice, and assuming non-correlated noise and a non-directional receiving antenna, the inverse square law would dominate and the overwhelming majority of the interference would just be the closest Tesla, not the total volume of Teslas.
Any chance they could unintentionally synchronize by interfering with each other? Many systems naturally do this but I'm unfamiliar with inverters on this level so I have no idea if it's feasible or not. Maybe car manufacturers have thought of this and intentionally use slightly different frequencies across vehicles or just shield their clock source from interference?
It would not surprise me in the slightest if someone has considered using coherent wave forming from electric vehicles as a targeting mechanism. In a malicious-actor scenario, EVs often have GPS which can provide a pretty accurate time-synchronization mechanism. With enough collected GPS points to eliminate significant error and fine-control over the inverter phase/frequency it seems that it would definitely be a possibility given the number of EVs in many urban areas. Heck, most EVs are even internet connected for software updates.
