One thing.
The system can auto correct.
For example, one person claims that such a vulnerability means that the insurance company won't pay, for it leaves no smashed windows if you are robbed.
However, all it takes is one person going to court, publicizing it enough, and winning against the insurance company.
What happens? The insurance company, naturally, starts to increase rates for owners of that brand of car.
It has to pay out more often, for that car has a weakness, and this is the result.
This has happened before, with cars that didn't have physical steering wheel ignition locks, back in the 80s.
The result? Sales dropped for those cars, no one wants to pay 50% more for insurance, and manufacturers quickly worked to fix the issue.
It's a sad thing though, to see a relentless stare at the daily, short term bottom line, without thought to other factors, and long term profit.
Way to drive away customers, and crash a reputation! Brands to steer clear of, to be sure!
