Honestly, we need something to push the electric infrastructure even further into the breaking point as it doesn't seem like there's going to be political clout to actually INVEST in our infrastructure until people are without power for multiple hours of a day due to rolling blackouts. Maybe if we revert back to where we have power that's as reliable as rural parts of India, people will wake up.

Also, regarding "supercharger abuse", I asked my Tesla support contact about using it for day trips and such, because I don't have home charging ATM.quote:Most of our clients only use the superchargers to charge. It will have no effect on the battery. So, please have as much fun on the weekends and use any and all superchargers until you can get charging set at your home.

Honestly I give zero fucks. Once I can afford an electric car that goes 250 miles on a charge, I will buy one. I don't give a flying gently caress about any other options or the price once it hits the magical price point of "something I can afford." Most of my friends are in the same boat. I will remind you that regardless of delays this dude is the same guy that has built rockets that can reliably resupply the ISS. I trust that he will eventually do what he says he has set out to do.

So with this. Yet, the things happened eventually. If there's one thing I am critical about right now, it is not battery-electric. That poo poo is excellent, from politics to pipe. The thing that sucks is Tesla's obsession with automation and self-driving. I was doubtful before, reading Tesla-drivers' experiences now makes me hate it - the flaws might be tiny but they are symptomatic of a developer mindset that is so far removed from the real world, it should not be deployed in the real world.

Despite being the most comprehensive review to date, it relies on "sparse data" and acknowledges that a secretive industry might avoid revealing high costs, or conversely might subsidise battery packs to gain market share. It's not just about "optimism." These start-ups need constant infusions of capital and hype is how you get it. Not to mention the fact that everyone making money off the speculation isn't in a hurry to get in touch with reality anytime soon. Also, in terms of design, the Tesla has some dumb issues (weird ergonomics, stupid touch-centric interface, and annoying things like not being able to turn the radio off ever) but in general pretty much all the automated driving stuff in the car seems to be licensed from industry suppliers and is no different from the adaptive cruise control that's available on pretty much every luxury car and even, in the latest redesigns, regular cars like Mazdas and Subarus. So far none of the promised advanced automation has actually appeared yet, and probably won't for a while. Dunno, what flaws have been pointed out?

All those things could happen. But, most utilities do not currently offer peak/off peak rates for residential customers. I'm not against EV in any way, I just think "don't worry about it, the market will adjust" is hopelessly optimistic. At the same time as EV becomes more popular, there has to be a push for efficiency, there is lots of needless waste in most American homes.

We have it, but at 16.6/5.6 for peak/off peak vs 9.4c flat I'm not sure it'd be worth it. That 16.6 cent rate would be killer during the day in the summer with the home AC on, you're not allowed to have a second meter with time of use billing.

I am honestly surprised that peak rate plans aren't a thing everywhere. Bad assumption on my part. Where I live (Phoenix AZ area) the rates are broken into Winter (November through April billing cycle) and Summer (May through October) for APS customers anyway. Standard rate varies by usage on a tiered plan where the more you use the higher per kWh it is: Winter - All .09417 Summer 1-400 kWh - .09687 Summer 401-800 kWh - .13817 Summer 801-3000 kWh - .16167 Summer 3001+ kWh - .17257 Peak / Off Peak rates: Winter - .19847 / .06116 Summer - .24477 / .06118 Except for the hottest months, my solar panels generate more power than I use during peak times, so I only get on-peak power from the grid from June through September, and my credits accumulated during the winter more than offset this, so I actually never pay a single penny for on-peak power.

Though sometimes university news bureaus trump up research findings for obvious reasons, I think this could be legit. Of course it takes some amount of time for any academic research to ooze into commercial activity, but with the attention on Li-Ion this might be a significant kick in the rear end for production, which would be awesome. I'm not sure if Tesla knew about this specific research, but of course they were counting on advances like what we seem to have here.
