People don't like the government telling you you can't leave the room you're in but if you break the law you go to jail. This is no different. As usual, anti-government people tend to miss the point completely and jump to extreme non-related situations. Having people who repeatedly break the speed limit have their cars adjusted so they can't do that but can still travel freely and drive anywhere they want is the topic here and you're talking about limits on free speech and government surveillance of our emails. This is not an authoritarian policy. If you break the law, you face consequences.
Extreme non-related situations? Not true at all. Cars are just computers on wheels. They can even be hacked. Remotely. They've got embedded cellular network connectivity. They've got microphones. They've got cameras. They've got goddamn privacy policies these days.
Governments setting policies on cars is just the transportation version of global mass surveillance and control. It's not your car anymore, and it's not you who's driving. The computer is controlling everything, and it's not your computer, it's theirs. If they can set speed limits, they can easily do a lot more than that, it's literally one mandatory over the air software update away.
The only question is: are you gonna sacrifice your freedom for security? The so called "anti-government people" made their choice. It seems you have made yours. The consequences will be felt either way.
