This.Bluetooth LE can be attacked. Turn on PIN to drive. Shrug and move on.
Since my pick up in 2020 this was one of the first things i did. 2 years on, and I've never (touch wood) had any problems. This isn't specific to tesla's either, and truth be told hackers will find a way, one way or another. I'm glad I don't need to worry about a relay attack as I did in my previous car - I'd keep the key in a pouch opposed to my wallet.
I walk up to the car, it unlocks, I enter my pin and drive off. Get out and it self locks. Only draw back is, if someone did want to steal it, they'll need my pin. Frankly speaking a car can be replaced whereas my (and my families) safety could be jeopardised as a result of the pin.
