Interesting to see him mention one particular item that has been in the car since Oct 31 (1.15.8, iirc), and he's showing V 1.9.0: 'idle creep' @ 5:10. They've been working on these videos for some time apparently.
I think the two chargers is indicative as well. The red one is early version, beta only I think. The silver one is the now shipping version.
And for the pre-heating... leave the door open a crack! Hasn't really been an issue for me yet, tho I'm looking forward to the remote app.
