And yet disingenuously you avoid the fact that centralizing the act of automating transit by delegating it to the manufacturers of an automated transit system is one of not the lynchpin to fully technologically enforceable tyranny.
You can stop a protest with a geofence with self-driving cars. You cannot stop every state's worth of pissed off people driving to the center of power and raising hell with human driven vehicles, maintaining the possibility of active revocation of consent to be governed at scales that require governments to come back to to the negotiating table.
Canada learned this the hard way with the trucker protests during COVID, and agree with the protestors position or not, you can't argue with the results. The federal government pushed the little red button by sanctioning their own citizens, freezing assets, trying to turn the tables; demonstrating to anyone paying attention we have already reached a point of technical centralization harmful to peaceful resolution of issues, as small groups are making decisions so vast, that the only response to things is to physically show up, and in doing so, scare the ever loving hell out of residents as a feedback mechanism to those causing the problems.
Those that look at self-driving as only a safety metric, and not simultaneously a sovereignty metric, are either crushingly naive, or haven't put anywhere near the thought into downstream effects as they should have.
