Your Model S can be stolen with a few hundred dollars of off-the-shelf equipment if you didn't buy in the last few months. Cars sold before June 2018 have this vulnerability, but not any Model X so Tesla has had the solution available for a few years without bothering to update things on the Model S. They will have a solution soon, but it requires software updates to your car. Apparently you have to replace all your fobs to get the new protection. A PIN-to-start feature was added to the car, but I hate those sorts of things and that is why most phones have gotten rid of it. How much should we pay to solve their sloppiness to get new fobs?
