There is no longer any such thing as "non enhanced AP" or what is often referred to as AP 1.0. Is has been replaced with Enhanced AP with 4 cameras, 12 new and improved ultrasonic sensors, and still includes one forward radar.
I do not know what "promise" you refer to. Please specify and provide a source.
If you ordered a Tesla without AP before the recent announcement of the new options of Enhanced AP and Full Self Driving Capability you will still get your Tesla without AP. I can't tell from your post if that is what you did or not. Your statement "people who opted not to get AP but we're expecting to only pay $3000-$3500 " seems contradictory to me.
The new Enhanced AP and Full Self Driving Capability options use new ultrasonic sensors that are more capable, according to Tesla. You can decide whether or not to believe them.
There is actually such a thing as AP1.0 with the new hardware it's being offered to those who ordered prior to the announcement and consists of 1 camera AP, it's just not publicly being offered, which is causing a problem and confusion because it is coming across as a shifty way to charge more for increased costs after a mutual agreed price.
The promise I'm referring to is this
https://goo.gl/images/1vD07V the text on the bottom of the option clearly states that AP can be enabled after for $3000 the reasonable expectation is that price is locked in for the customer, otherwise it would contain fine print or parentheses something like "price subject to change"
If they don't stick to the reasonable expectation they are opening the door for bad things to happen.
I'm assuming their plan is to always make the AP 1.0 equivalent available to maintain that expectation, I'm thinking they just aren't advertising it in an effort to push people toward APE
If they don't have that AP 1.0 option available then they pretty much have to either make APE available for the price expected which isn't fair to the people who are being told they have to pay the difference if they want APE.
The simplest solution to this whole mess is to simply put AP 1.0 on the order form for the last price listed, either that or give APE for the price expected.
As for me im all in, the nerd in me couldn't handle not having the self driving Capability.
