I'm so glad you took my response reasonably... lotsa people on this forum launch if there's any disagreement.
From my perspective, I plug in every night. My longer daily drives are about 230 miles, but typically under 100. I understand I may be spending about 50 cents per night to pay the vampire. I find that very mildly annoying, but certainly not my highest priority... in fact if 5.6 offers option, I'm likely to leave sleep mode off. I suspect that there are lots of others in same situation, and of course most of them would not bother posting because generally posts on this topic are from the people who find it unacceptable.
Nonetheless, since a large sample have concern, I agree it is a priority for Tesla, and they seem to agree too. The fact that they've tried to roll sleep out twice is evidence. Unfortunately, it's about the most complex thing they could undertake, and each time there have been unforeseen issues. Looks like 3rd time is the charm.
Just to show I'm not totally tolerant: What is horribly unacceptable to me is an iphone that won't stay charged all day.
