Despite all the FUD in the comments, the Comma is the single best thing I've ever added to any car, ever. From now on, I'll only ever buy a car that's compatible. It makes me feel safer by a huge margin (I might or might not have fallen asleep one night on a long road trip and awoken to my car driving along happily, and there may or may not have been numerous times when my car stopped me in time). Driving fatigue is nearly eliminated, and comfort for passengers is higher.
It's far better at driving than either FSD or Autopilot, though it doesn't navigate or change lanes without input, but for long road trips those things don't matter to me at all.
