In some parts of Europe, digital attacks on proximity unlock systems are becoming a common way to break into cars. Especially for a system based on Bluetooth, it's difficult to defend against an amplification attack. The key here is that one person can make a tool and sell it to many common criminals, and even if the auto manufacturer notices that they are doing this, there isn't an easy way to patch the issue. For something like a Tesla, it's difficult to imagine a software vulnerability that cannot be fixed with an OTA update, but for a manufacturer that doesn't have OTA update capabilities, I could definitely see cyber hacking tools being distributed and used in a similar way.
