Answers:
1. Rear visibility: Poor,same as gen2 Volt, unless you get the Premiere with the added camera rear view mirror, this is Great!
2. It is pop open.
3. Yes, it defaults to 8 amp charging, but you can set a home location to default to 12 amps.
4. There is a shorter dam directly in front of the front tires, which means it will almost never scrape on any dips or even curbs.
5. I would guess it's efficiency is diminished at over about 60 mph, but I didn't specifically check it yet.
6. It might be a little better than the Volts, but we haven't had much moisture in the air around Fresno for years, so It is hard to judge that yet.
7. I have never coasted in any car ever, so can't relate to that. However, the handling is at least as good or better than the Volt, IMHO.
