Should Tesla get to decide what roads you can drive on?
But they should _obviously_ be able to dictate which power utility companies used to charge the car. Nobody knows what ampere or frequency non-Tesla electricity comes in. Only Tesla knows how to delivery electricity properly. /s
Regulation makes sense if there's no alternative to (easily) switch to, but that also means that the first principle of a regulations regime should be to create the conditions so that all possible alternatives can flourish. Failing that (as I think the EU has with software tech), restricting incumbents is the logical choice.
What if it's a terrible idea, but is outweighed by other good decisions Tesla makes? Should they be encouraged to ruin things just enough that it's still worth buying their products? As long as the ppm is just above lethal limits, does it matter who is poisoning the well?
Remember that Tesla can just send a OTA update to remove artificial software limits on the same battery capacity during disasters (Model S and X with the same battery capacity).
