Does the Model 3 have an API? I wonder if aftermarket or DIY knobs and buttons and gauges would be possible.

My car probably shouldnt have an API.

  An API for non critical functions is fine: radio, air con, etc. Probably only want a read only one for everything else though.

    Generally what goes for an API around here involves a javascript library, a internet connection, and a sizable amount of data transfer.. and to remotely control something like a thermostat 2-3 feet away from me I have to send packets half way around the world - I'm okay without any of this. If I want to control shit over CANBUS I can.

  There's already a standardised bus for data transfer between systems (canbus) so why not an API?

    I would rather just connect thru CANBUS

It kind of does. All modern cars have an "on-board diagnostics" port that devices can plug into to get information about the car, including while it's moving. There are various devices you can buy (Verizon has been marketing one called Hum a lot recently) that can connect to the OBD port and do various things with the information there, such as send you a text if your kid is driving it too quickly or if the car is reporting a fault somewhere. This connector is the same one that service garages hook their diagnostic equipment up to to when you take it in. I'd imagine someone clever enough could wire together a speedometer which connects to the OBD's connector and shows a current speed, though I'm not sure if there are compromises on resolution or sampling time or that sort of thing.

It has CANBUS. It’s essentially an observation and control bus for all vehicle subsystems. You can interface with it directly with the proper equipment and knowledge. https://en.m.wikipedia.org/wiki/CAN_bus https://en.m.wikipedia.org/wiki/CAN_bus https://skie.net/uploads/TeslaCAN/Tesla%20Model%20S%20CAN%20Deciphering%20-%20v0.1%20-%20by%20wk057.pdf https://skie.net/uploads/TeslaCAN/Tesla%20Model%20S%20CAN%20...
