I got a Comma autopilot for my car. AMA.

Well, is it any good? I recall seeing footage from a year or so back (an LTT video?), and thinking it seemed pretty solid. I'm curious if it's "Waymo-like" (you can pretty much stop paying attention and trust in the machine) or if the error rate is high enough that you're on edge throughout.

How difficult (or easy) was installation?

They advertise a 15 minute installation process and I think that's pretty accurate.

Basically, your car has a camera for its stock ADAS under a plastic cover behind the rear view mirror. You pull that cover off and patch in a wiring harness that lets the Comma override the signals from the stock ADAS and replace it with its own. Then you close that up, loop a wire out of the harness you just installed into the Comma device that you mounted on your windshield, and voila.

It ships without the autopilot software, you have to connect it to wifi and download it. This is pretty easy, though the process for connecting to wifi was slightly unclear.

The first time the autopilot software boots up it asks you to drive manually for a bit to calibrate itself to the way it is mounted in your car (pitch and roll angles mostly). Then you just activate cruise control the way you normally would, and the Comma starts driving.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
