Tesla didn’t delivered on its intended mid-December software update of Enhanced Autopilot as initially reported but it is giving something before 2016’s end. Elon Musk recently revealed that the new autopilot software will reach 1,000 HW2-era, which is October and beyond cars with rest of fleet of HW2 will get the in the following weeks if there is no hiccups. On January 5th new update for The P100D performance update should hit so you will get something extra if you splurged on a recent Model S or X.
“Resolving an Autopilot HW2 bug that shows up when booting from a subzero cold-soak. If that fix works, software will start uploading tmrw.” – Elon Musk
“HW2 Autopilot software uploading to 1000 cars this eve. Will then hold to verify no field issues and upload to rest of fleet next week.” – Elon Musk
But if you are the part of majority that isn’t using HW2 then prepare to wait though Musk said that the autopilot update will hit in late January. These type of delayed update is understandable because the newer models have more latest sensor hardware than the older models but it also suggest that you should get used to gaps between updates of different models, Specially when they will rollout hardware-specific features.
