What does this thing do? The sales page doesn't help much either "The comma 3X is custom hardware designed to live in your car, and purpose built to run openpilot." What is openpilot??

To me this just looks like a generic dashcam

It's really not hard to just search "openpilot" and click the first link. There's also a link at the top of the comma.ai website that links to the same page.

https://comma.ai/openpilot

It is an advanced driving assistance system. It kind of drives your car for you (lane centering, basic obstacle avoidance, and adaptive cruise control all without you have to touch the wheel or the pedals) as long as you’re looking forward and paying attention to the road.

They have demonstrated full self driving capabilities with a car driving “itself” to Taco Bell. I have a comma3 and have never had much success with that feature. The car drove itself very slowly and seems to just weirdly creep through stop signs. I think the last time I tested that was over a year and a half ago, so it may have improved.

I use mine only on the highways. I noticed for long trips (6+ hours), I can drive longer distances in one go and not feel as fatigued when I reach my destination. As an example, a 10 hour trip to visit family (11-12 hours including stops) I can do by myself in one day with the comma device instead of stopping halfway, or splitting driving time with someone else. For shorter trips (3-6 hours), I arrive to my destination with more energy than when I drive without these features. I am also able to focus more on potential obstacles further down the road than without it.

I think my device has already paid for itself thanks to a couple year period where I had to do that 12 hour trip I mentioned a couple times per month. Plus it is a really nice dash cam.

Are you tuning out closer concerns like lane keeping or smaller objects?

How can you be confident the system is at least as reliable with the concerns you are less focused on?

> How can you be confident the system is at least as reliable with the concerns you are less focused on?

That's my current heartache with my Comma: it does a stunningly shitty job about decelerating into brake lights ahead, choosing rather to keep accelerating (or I guess keeping speed) and then slamming on the brakes as it gets a few feet from the car. OT1H, it's never actually put me in danger, OTOH I don't want "next time" to be the bad luck

Not only does that make me super nervous, it's also a rear-ending risk (since the poor Comma can't see what's behind me)

I haven't worked up the nerve to build and flash one of the 18 quadrillion forks onto my Comma; I've heard some of them are better, but that some word is doing a lot of work

I'm surprised you've even had any success. Are you a Comma Prime subscriber or something? Because mine absolutely gives no shits about red (or yellow!) lights, stop signs, "danger, sharp curve ahead," nothing. If it's the open road, lucky me. If there's the slightest decision to make, best to disengage

The US government made them tie their hands behind their back a few years ago, NHTSA tried to shut down the company so they rebranded their then Comma 2 as a dashcam that might be able to drive your car.

Golly, sure is great regulations to protect pedestrians and other road users are trivially bypassed or bought off. /s
