AP2 remains deficient relative to AP1 for 4 additional reasons:
1. AP2 does not react to speed limit signs as does AP1. It relies upon an error-ridden database, the net result of which is either AS driving too fast in school zones or too slow on highways (examples of both cases have already been enumerated). Clearly, an AP3 solution that offers both would be the win here for dynamic adjustments with database backup.
2. AP2 brought us phantom braking - triggered by the occasional overpass, adjacent stationary vehicles, gremlins, and rifts in the space-time continuum.
3. Less information in the IC - no vehicular differentiation.
4. AP2 crosses the double yellow and other lane demarcation. Rarely did AP1 ever do this, and AP2 does this with alarming regularity.
The characterizations that AP1 is more stable and AP2 is more like a teenage driver are fairly accurate.
Eventually AP2 will surpass AP1 or at least that’s what the marketing materials tell us, given the extra cameras and sensors. Meanwhile, both continue to improve.
I regret the purchase of my AP2 car. Had Tesla been less dishonest in late 2016 and early 2017 in particular with regard to AP capabilities as well as included supercharging disappearing and reappearing 6 weeks later, I would have kept my AP1 car and saved easily $35K and counting.
Fortunately, there are more AP1 cars coming off lease now. The other day I met a fellow at an SvC during my now twice monthly visits and he had... brace yourselves... a pre-owned P85+ that may have the parking sensors*... I’ll pause here to let that significance sink in
* It was the case that having the parking sensors meant that the car was AP1-capable. The current owner will investigate. P85+ cars, which also have the added benefit of being RWD, that are also AP-enabled are almost as rare as these:
