The experience of learning about Comma, buying a dev kit, downloading a separate software package, flashing it to the device, wiring it up to your car, etc. (vs. just having it there on your Tesla, and everyone's heard of Tesla) is the source of massive selection bias.

If you're competent enough to get Comma running, you're probably technical enough (and invested enough!) to read the instructions and understand the operational limits of the system.
