Polo-Rican posted:Mass adoption of huge electric SUVs would probably be way worse for the environment than the current status quo. How do you dispose of millions of 2000lb lithium batteries that would inevitably end up in junkyards every year Yeah, the batteries are the part I'm worried about long term. I've seen how long laptop and power tool batteries (don't) last and while I'm sure they'd use something higher quality for car batteries I have a lot of questions about how long they'll last and what will actually be done with them when they need to be replaced. Never mind the lithium mining that will be required. We might just be trading one environment problem for another.

That was fun riding around with. The momentum was very real though, you didn't want anyone to get in the way (also the brakes were poo poo) and turning was at low speed. Most of it was just ads that were distributed more or less directly into the bin.

Also, with manufacture and extraction factored in, it's not so much trading in as it is just adding on.

do gooder idiot dems teaming up with car makers to make ultra heavy ultra fast vehicles mandatory is so incredible. why yes, we want to make everything more dangerous, destroy roads faster, and make things incredibly inconvenient for actual driving to where these cars will be used in addition to regular ones all because they got embarassed by boring hybrids and plugin hybrids coming out a decade ago and needing to pretend that the LAUNCH MODE vehicles are angels from heaven

They have the same discharge/recharge life cycle degradation, where battery life starts to decay after a while. One of the tricks is to under rate the battery, giving it an invisible buffer on the high and low end, so the battery decay doesn't show up until the battery has already used up that buffer. Lithium iron phosphate batteries have a longer life, and are starting to show up in more applications. They're really popular with off grid/solar battery people right now, because they're rated to last 10-20 years of daily cycling.

mawarannahr posted:apparently there's a shortage in good iron. do you need the good "direct reduction grade" iron for that? https://www.spglobal.com/marketinte...n-push-70947714 Turns out you'd just need a shitload less of every rare or difficult to extract resource (not to mention energy itself) if we focused on making more efficient vehicles that were more suitable for the task they actually perform. An e-bike or a golf cart do just as good a job and hauling some groceries home from the shops as a 9000 lb hummer EV with a single person in it, which is going to be like 90% of their market-wide lifetime usage. The average EV uses about 200 Wh of energy per km. An e-bike is closer to 6-10 Wh/km. Both will adequately perform the vast majority of trips people currently use their cars for. The e-bike will clearly use less of everything (energy, lithium, rare earth metals, regular construction materials, consumable rubber tires and brake pads etc.) vs. the electric car, again to perform the equivalent job if we assume the city, society and legislation you're operating in make cycling instead of driving at all viable. I don't know what the answer is at the end of the day, beyond moving and living somewhere it's possible to not need a car (which probably means nowhere in north America).

This week I ditched bike share and city streets and have been commuting into work with my own bike and through the valley. I barely have to touch any roads, have okay bike lanes when I do, and it's just loving glorious.

Idiots. It happened a couple times more during our work but not as a close. It really drives me crazy, because it’s so dangerous and awful. We should put speed bumps at stop signs.

That's terrible that that bus driver will have to fill out a bunch of paperwork, and almost certainly there will be some scheduling impacts from people riding the bus. A real shame the truck will likely get paid for.

no notes https://www.thestranger.com/i-anonymous/2023/04/12/78945092/driving-dunces quote:Around rush hour on April 4, traffic going up Olive Street stopped for a pair of pedestrians crossing Harvard Ave. Incurious as to why traffic was stopped, you sped around the stopped cars, nearly killing one of the pedestrians. A difference of seconds would have cost those people their lives. They said they were okay, but they were visibly shaken.

There was a hilarious picture of a car trying to tailgate which got wrecked and told to pay for the damages to the bollard.

Let's you do large areas because residents, deliveries (often with restricted hours), emergency vehicles, buses etc can drive in but there's a vastly reduced requirement for enforcement by police, fine etc

Had some Karen on a bike block my attempt to make a right turn. Waved her hand at me dismissively, so I laid on the horn and gave her a reckoning she won’t soon forget! E: was on foot, to be clear. gently caress cars ftw
