Yes they can, they will come boot it or tow it or remotely deactivate it, if you finance from them instead of the bank and stop paying. And they won't give it back, and you can't decide to pay later.
There absolutely are multiple car brands on the market that can be remotely deactivated: "A Quebec teenager's car was remotely deactivated by a dealership after he refused to pay to remove a GPS tracking device" https://www.youtube.com/watch?v=Y8Enmspjbjo
"How auto lenders can disable your car if you miss payment" https://www.youtube.com/watch?v=n6LU20sAn9c
This vest thing was spun as a subscription model dystopia, but that's not really what it is. This is really an actually very consumer friendly financing plan, it was just marketed badly and then framed as FUD by Vice.
Think about it- this is a financing plan where you get to pause for the winter because you're not using it. Neither Volkswagen nor the bank offers that kind of flexibility.
