Tesla FSD 12.5 is 3-5 Times Better

Crowdsourced data (at Teslafsdtracker.com) shows that Tesla FSD 12.5 is three to five times better than FSD (Full self driving supervised) 12.3.6.

The FSD 12.5 is showing 744 miles between critical disengagement and 111 miles between any disengagement.

The FSD critical disengagements improved 3.8 times from 194 miles with 12.3.6.

There was also a 3.8 times improvement from 29 miles to 111 miles for miles between any disengagement.

There was a 4.33 times improvement between city miles to critical disengagement.

The city miles to disengagement are better than the highway miles to disengagement. The highway miles is still using the Autopilot software stack. The FSD software will be unifying city and highway software which will substantially reduce disengagements. Tesla will only switch to FSD over Autopilot when FSD is clearly statistically improved over Autopilot Highway. There will also be no issues when handing off between systems after a unified software stack.

The disengagements are maps, potholes, speed and obstacles. There are almost no lane issues which was a main problem in 12.3.6 and earlier versions. The critical disengagements could only be some fraction of situations with other cars and obstacles at this point. The obstacles disengagement issue could be something more simple that is fixable with FSD 12.5.X.
