Comment Re: Lifespan of cars in the future (Score 1) 19

"Cars have never been built to last."

Not as a general rule no, but Mercedes cars of the seventies and eighties were. They stopped making them like that in the nineties, though.

Japanese cars of the nineties, with some notable exceptions which were in the minority, were designed to be easy to service. Alas, that also stopped.

Comment Re:Just couldn't resist, could they... (Score 1) 77

I once heard someone say that the homeless in Cali sometimes do actually have credit card readers.

Not saying it isn't happening but I haven't seen this yet, but I do know for certain that a lot of homeless people have cash app, and a few have venmo. They certainly could have readers, as square still gives the first one free, but I doubt it would get them any significant amount more money than using payment apps.

I presume most free phones don't do NFC either, but I haven't tried to find out. Maybe next time I walk past a free phone ez-up I'll ask, but they probably won't know anyway.

Comment Re:Yeah, tracking devices for everybody! (Score 2) 275

You know, the irony is that I'm less worried about the tracking portion than the fact companies will use it to jack up insurance rates on people... or try to track whether or not women are pregnant in Gilead states.

You're less worried about the tracking than the tracking?

I thought EV batteries were supposed to be properly sealed.

I don't see how they could not be vented, as they are not 100% full of stuff and that means the air inside of them is going to be expanding and contracting with thermal cycles. A quick glance around tells me that they both have pressure vents (in case of cell failure) and selective permeability vents (e.g. from ePTFE) which handle typical expansion and contraction venting, and try to keep moisture out.

It's a lot less dangerous to ship them mostly discharged, like maybe at 30%.

True, but nobody wants to ship lithium batteries at any lower a SoC than they need to, because being stored at low SoC damages them permanently. When I bought my LFPs the documentation said they were shipped at a nominal 50% SoC, which the documentation also explained actually meant they were shipped at 70% SoC. The premise is that they self-discharge, and you don't want them falling too low before they are used. What if batteries (or vehicles with batteries) wind up sitting around in a port somewhere for a while because of some SNAFU?

The electrolyte of NCM batteries releases oxygen when heated even below the point of actual combustion. This is part of why they have lower combustion temperatures than LFP, where this doesn't happen. NCM batteries should be outlawed because they are all of: 1) easier to cause to combust, 2) more difficult to extinguish, 3) far more toxic when burned because of the cobalt in particular, which LFPs don't use.

Comment Re:Now you're cooking with aluminum (Re:cheap EVs) (Score 1) 136

Neither Ford nor Chevy have any trucks with aluminum frames.

Ford has fully aluminum pickup truck bodies now. Chevy uses some aluminum parts.

Some cars are starting to use aluminum subframes now instead of steel ones to reduce front weight. Model S, R1T, Camaro, Audi Poop (etron), Porsche Taycan, Jeep Cherokee...
