Rainy days hit different when @comma_ai Openpilot is doing the work. Just vibing, watching the rain, sipping coffee while it handles the road like a champ. This is what relaxing drives are supposed to feel like. Never going back.

Total comma four engagement has passed 9,000 miles now. Hands-free through beautiful rural Wisconsin backroads. My @comma_ai device engagement has come close to 93% since I installed it back in February. That's 93% less driving I have to do on the daily.

Today my Rivian chose violence and decided the road I use highway assist on everyday is no longer available.

Time to get a Comma 4. It’s way better at everything.

I'm about to pass 15k miles on my Comma 4. Can't remember where I was on the 3x before moving up, but I know it was a bit more than that. I engage as soon as I can, every, damn, time.....
