I presume you're referring to Autopilot/FSD. I don't trust it at all, don't use it on my Tesla, and will not get into a "robotaxi" using it, but it's an optional feature.
Autopilot aside, though, the regular boring car software bits are rock-solid, and I've never had an issue with using it or after an update.
