What specifically is the issue about retiring in a 'blue state'? If you mean cost of living, the OP might choose Needles CA or some place that is much less expensive than, say the Bay Area. Is there a tax you're referring to that is problematic (i.e. cap. gain tax on investment income in state) or just the hidden taxes (i.e. taxes on fuel etc)?
I've not visited most of the top 10 on this list, but I wonder if what you trade for COL improvements makes up for the experience of living in those locations. (A complex question if you factor in commute times, community factors and personal interests at a minimum.)
It seems that your demo page (.../demo) is broken (it's 404ing with a NoSuchKey).
Anyway, I'm wondering if your solution helps users who forget their password? (Though I notice your initial comment says something about "get rid of passwords all together.)
"I also need to improve my accuracy for numbers and sybmols — but again, this will come with time." - oddly enough this hasn't been the case for me or at least as much I as I would expect. I believe it would take a concerted effort--though there are some symbols that I'm much more proficient at. ~ is not one of them!
"There are unique challenges that come with working on these cars. You might have to rebuild a circuit board one day, and fabricate a new hood the next day. Actually, if any body parts are damaged, you'll have to fabricate them. Tesla doesn't sell parts to anyone, so Medlock has taken to fashioning new panels out of carbon fiber himself. "
Didn't expect to see circuit board rebuilding until ~2023 (15y is my recollection for MTBF curves starting to climb).
