> how would that car get access to Internet, if wireless providers are controlled by the USA ?

> Verizon, ATT, Tmobile and their APNs are controlled by the FCC, and any regulation can force vehicle traffic to be isolated if there is credible threat.

This response would *not* be soon enough. One response from a server, and the car could be bricked forever, explode/short circuit causing a fire, self-drive into the nearest government building, etc. A car is a huge weapon, especially when remotely controlled. This software could be pre-installed from the factory, with commands injected via side channels. I could imagine a hundred ways to do this.

> but, why would BYD or other nation sabotage its own future profits by bricking cars?? it doesn't make sense.

I'm precluding this situation with a background level of hostility between nations... they don't care about maximizing profit, but maximizing damage. It would be a government stepping in forcing this.

its pure paranoia. first of all, I as a consumer, mature enough to understand risks and carry them myself, I dont need no government to babysit and censor what I am allowed to buy.

second, you assume China will resort to bricking civilian cars, when they have better options like actual weapons. Bricked car can easily be towed away, there is no way China can cause damage.

the best way for China is to keep manufacturing cars and selling them to USA for $$$ - this will ensure the relationships are beneficial to China (mutual trade is better than military conflict)

You have the tools to reverse-engineer every single chip in your car to ensure they aren't backdoored?

> second, you assume China will resort to bricking civilian cars, when they have better options like actual weapons.

Again, my argument has nothing to do with China, I'm simply saying cars would be a great thing to weaponize. Much easier than smuggling a weapon into the US, you just sell a car to a consumer and you have functionally a remote-controllable bomb.

> Bricked car can easily be towed away, there is no way China can cause damage.

Not if it's driven away and used in an attack first. did you read my reply? You still haven't actually responded to my point that internet-connected cars would be an excellent weapon by a hostile nation.

[slt2021]

I dont, but there are plenty indie hackers who would be happy to buy cheap $10k car and reverse engineer it.

Any backdoors would be easily detectable and preventable just by .... not connecting the car to the Internet, or folding connection to isolated VPN not accessible from the outside.

all vehicle traffic can be inspected and sinkholed with IoT firewall, if you really want it

[sodality2]

Not when cellular or satellite chips are very well hidden... You might not even know about them, let alone have the ability or knowledge on how to stop it from connecting, force it through a VPN/firewall, etc. You already can't do that with desktop PC's thanks to things like Intel ME.

[slt2021]

I would be concerned if US Space Force could not detect rogue low orbit satellites from adversaries that provide uplink to imported consumer vehicles

[sodality2]

It could use any existing commercial service. Again, you could very feasibly set it up to be plausibly deniable until it's not.
