Only electric vehicles that support unlock via BLE proximity.

However, it will impact all electric locks that support this very same functionality as its a fundamental limitation of how BLE is implemented on cell phones. Trying to be more prescriptive on the latency or other parameters under the locks control will make the user experience significantly more frustrating and unreliable, crippling the feature.

Some car manufacturers are employing ultra wide band for precise location. The VW ID.4 for example has this. I'm not aware of successful (relay) attacks against these kind of systems.
