Crowdsourced results show that Tesla FSD 12.3.6 should have the best disengagement results for any version prior version of FSD. FSD 12.3 had slightly better city driving results but usually the reported disengagement results improve from the first days. It would be a very solid result for 12.3.6 to get over 300 miles for city and highway driving.
Tesla should release FSD 12.4 by the end of next week. If FSD 12.4 gives speed control, intersection creep and improves lane choices, then half of the disengagements would go away. If FSD 12.4 gives integrated reverse then the car would be able to get out of parking spaces for a far better end to end experience. It would go from parked, drive and parked again for almost no need for driver interventions. 600 miles between disengagements would be only one or two disengagements per month.
