Comma AI self driver assistant

Comma 4 coming. Seems kinda meh. comma.ai — make driving chill

It has theh same chipset as the Comma3x, it's just a new small form factor. Which is nice in some ways, and not so much in others. Given all the cool stuff @tonesto7 stuck on the UI for us (radar overlay, hybrid battery status etc), you would lose all that with a tiny screen.

They also announced an external GPU which will work with the Comma3x as well. To me, that is the big announcement. Should allow the models to solve much further out.

Radar overlay is probably my favorite feature, especially the speed of the front vehicle.

It is my favorite, but my family hates it. Because now I know exactly how slow they are going when I start complaining.

Hey, actually, does anyone know if there is a way to tune the following deceleration rate? I always have maximum follow distance set so it's extremely unnecessary to slam on the brakes when my lead car gets brake checked. Sure, they rapidly decelerated and the comma should slow but I don't want the follow distance adhered to so rigidly.

No, that is coming out of the model. It's the number one reason I don't use OP long and stick to Ford ACC.

Outside of the random brake checks for no apparent reason, I like the OP long over the stock Ford ACC on the Lightning. Ford ACC always seems to pull up right to the rear bumper of the lead car and slams on the brakes anytime a car merges in front of you or slows to make a turn

Can I still buy comma 3? Or can I use this with the old mount that you can screw on the mirror holder? I don't want to stick it to the windshield.

Interesting to see how low comma 3x will sell on ebay now. I just bought the coupler and 3D printed the mirror holder and the sliding part. I hate to glue anything on my windshield.

Ok, lightning adapter arrived update.
I should have waited until the adapter arrived before making my last update, but it's here now, and I've tried it with two known-to-work USB cables, and I'm still getting errors. same errors on the truck and comma as before. The comma shows "canbus disconnected: likely faulty cable," and the truck throws a number of errors that all go away when the comma is unplugged.
I thought it was going to work this time. The comma came up all the way to the point where it was drawing the green path and then a few seconds after came the errors.

I’ve had a hard time keeping all the conversations separate. Have you tried with just the short USB c cable that comma shipped? Obviously you have to pull the device off the windshield for that test.

No worries. Yea that is one of the ones I have been using to test. At this point all my testing is done off the windshield. just have the side pannel open for easy access with all the cables

Let me make sure I'm up to speed

IPMA --> Comma Harness --> Short USB-C --> Comma3X = Errors
IPMA --> Comma Harness --> Short USB-C = No errors?

If that is the case, then you most likely have a bad harness box or Comma3X.

Since this is your initial setup, I'm goign to assume you are in the 30 day return window. You can try to open a support ticket, or just buy replacements and see if they fix your problem. If they do just return the bad item with a sticky note telling them it's bad and you already bought a replacement.

Yeah, I'm going with bad comma3x. I've had it up and running for almost a year with little to no issues until recently. I originally had a modified (extended with resistors) Ford Q4 harness. Bought a new harness and lightning adapter to eliminate that. So I have all new everything except the comma3x itself, which was bought on black friday last year.
Suppose Ill get a support ticket with them started.

I wouldn't mention that you used a modified harness. ItjJust gives them an easy out. I wouldn't mention the coupler either. Stick to the simple fact that you have a new harness/box/and their short cable and you still get errors.
