This is a surprising statement. My recollection is that car manufacturers have made cars far, far harder to steal than they used to be. Possibly it's just an insecure whataboutism, but I don't think car recovery is first on the list for most people in terms of car crime.
Literally, just watched a video of a bunch of kids breaking into a Kia and driving off with it with nothing more than a screwdriver and USB key. And the USB key wasn't being used how you think. It could have been a chunk of wood. But in this day and age a USB key is easier to find.
We could implement a law that fines car companies who are in the top ten list, and pays out to the car companies who are at the bottom.
And car companies DO get fined. Kia was fined (lawsuit) $200MM in USA for not using modern standard anti-theft tech in order to save money.
Insurance companies DO give you a discount if you use the chubb or install other anti theft devices.
Economic incentives work!
Or you require dealers to make a disclosure at the time of sale to the effect that the car does not meet modern security standards.
Incentives work both ways. Most new cars have the computer hardware to solve this problem with a firmware update.
Sounds like the cars were made nearly uninsurable, and the manufacturer pulled it back from the brink, perfectly illustrating my point.
(and greed on behalf of the manufacturer)
