Per their training:
openpilot is a level 2 DRIVER ASSISTANCE system. It cannot drive on it's own and will never be able to drive on it's own. If it's not driving how you would like, you are responsible for correcting it. If this is something we aren't communicating well, we are very interested in fixing that. This isn't some wink wink nudge nudge crap.
We have a 30-day no questions asked money back guarantee, I suggest you take advantage of it. We would much rather that anyone who isn't ready to quickly correct any mistakes or thinks this is a self driving car not use it, as you are a hazard to yourself and others on the road.
Having ~95% of the driving taken care of sounds like sitting in the passenger seat when driving with a new driver, who still needs some instruction/oversight. Cool technology but hardly chill!
Google "accidents with comma.ai" and read some critiques before you buy.
BTW - Do car insurance providers provide a discount or charge a premium if you have this?
