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.

When I last looked at it, there was no navigation. They had disabled it as an experimental feature, because apparently it was really bad, and the rumor was that they were going to focus on other features with no estimate for when it might come back. So it's not a system where you can set, "I'd like to go to X," and then sit back and let it take you there.

I don't expect navigation to ever be a truly solid part of Comma, simply because it only has forward-facing cameras, so it can't merge on freeways or make turns that require checking for traffic by itself.

The other complication is that navigation databases are so bad that they even make humans make wrong turns. Google Maps is constantly telling me to turn onto roads calling them by names that don't exist on any road sign anywhere. For example here in Minneapolis, a certain road leading out of town to the south is called "highway 65" by Google Maps. Zero actual road signs call it that.

Maybe an autonomous navigation system will have a better time just because it cares a lot less about what roads are called, but unless the navigation databases include things like which lanes of freeways fork off into which directions, it still needs to read those signs.

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!
