In each of these 3 examples the person with AS is actually being considerate
I agreed with all of your comment but this: the person with AS is not "being considerate", when "being considerate" is defined to include modeling the likely preferences of the person you are supposedly "considering."
In each case, the "consideration" is considering themselves, in the other person's shoes, falling prey to availability bias.
Personally, I am very torn on the doorway example -- I usually make an effort to hold the door, but am very uncomfortable. I think it will help to remember in future that the availability bias of my own preferences shouldn't rule out being considerate of what the likely preference of the other person is... and to change my SASS rules so that I feel good about holding the door, so it's self-reinforcing.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
