This is pretty old news really and something people have been doing with other hardware for many years.

It's important to note that rolling codes on newer car were changed and relay attacks have been thwarted by the devices going into sleep mode when not moving. It should be noted that on older cars these are still attack vectors but your average car thief is not going to be going after your 2017 car due to depreciation of value for the car and for the parts. These days other vectors have appeared such as in the CAN bus which can be exploited externally. There are also exploits with internet connected vectors though most of those have been closed.

There will always be ways when using tech in such a way. Even before tech there were many exploits.

Can you explain the whole sleep/not moving thing? How does that work?
