affordable Chinese EVs
A Trojan Horse of monumental scale. China's long term goals is to run the world, they will use any opportunity they get to get economic control over other countries. Putting millions of vehicles on the road that can be disabled by the Chinese government every time we disagree is not a smart move.
And this isn't just fearmongering about Chinese tech, all modern cars have cellular modems and can be disabled to some degree by the manufacture, but China has 100% control over big businesses. If they say no commuting in Canada tomorrow, it'll happen.
The only reason there isn't more outcry about John Deere is they have successfully painted farmers as the bad guy, trying to "steal" business away from the poor tractor corporation. Same goes for 3rd party repair techs performing "illegal" modifications to iPhones.
