Quite the generous timeline on this person's behalf.

There is security that protects users and then there is security theater that provides litigation protection for the company.

Sometimes overlapping, but they are not the same thing.

This is my primary concern with modern cars. You are at the complete merci of the security and correctness of the cloud management software for the correctly functioning of the car.

Wouldn’t it be better if your phone/devices would pair directly with the car, exchange keys, and have the company cloud only function as a proxy.

On holiday a guests BMW didn’t want to “start” anymore because it couldn’t phone home because of lack of phone reception. They had to contact the dealer at home and move heaven and earth to get some dealer code to allow the car to start again for a while. Why is this even allowed?

I love this sort of content on HN. I am very curious what the impact of powerful AI has on these type of things
