It looks like a promising piece of hardware (though I am not sure if it's an RPi Zero they're adding BT and Wifi to, or actually an RPi Zero W - which would be easier, you'd think). My last two cars both put their OBD II ports exactly where my left leg is under the steering wheel, so I hope they ship it with a short right-angle extension cable (I use a much shorter BT dongle to connect to my phone current, it doesn't project too far).
