didn’t know how hackable cars are:

- modern cars send messages from the electronics through to a bus (engine, wheel, breaks, etc)
- they almost all use the same protocol “CAN” bus
- can just plug in a compatible device, intercept and start sending messages and the car just does it.

This is how comma.ai open source self driving car add on works.

cool talk

Grat resource.
As I know volkwagen has a registry in the main control unit that labels rogue units as foreign and does not allow the car to start the “ignition”.
But otherwise can is just a simple broadcast protocol. Anything hooked to the obd or any other connector can snif the data of all devices.
Should add that many modern cars adopt a parallel optics cable for high speed multimedia data but is often used for other high transmision sensors too

Its an “old” simple protocol
Needs something smarter on top of it
Unfortunatelly is a one wire or 2 wire low bandwidth protocol.
To achieve speed you sacrifice security.
Was not meant for smart cars 😂🤣🙈

I was very surprised they’re not authenticating messages.

Pretty cool how open it is.
