In early 2020 I used a Comma 2 on my Honda Civic for a few weeks.
It had one failure, but the way it failed was so alarming I'm hesitant to ever try them again. It not only failed while engaged, but it froze which meant it still showed the bright green outline indicating "I'm still engaged!" with no alert sounds, visual indication of disengagement, or automatic restart.
I only noticed something was off when my car started to drift outside the lanes during a curve, which took me longer to notice than necessary because it still looked engaged and it looked like a somewhat typical case of understeering until I started exiting the lane. It also never booted back on again, so something went seriously wrong during an otherwise routine drive.
Stock driver assistance systems (e.g. Rivian Driver+, Tesla Autopilot) have redundant computers it can fall back on if the primary fails. If Comma offered a self-contained device that was demonstrably redundant at a hardware level I'd be willing to give it another shot!
