Pedaling warms you right up :)

Warm is not the same as comfortable. Listen, I'm from alaska and have several family members who routinely ride bicycles to work and around town in the winter. Except when it's storming. Except when their hip hurts. Except when it's breakup. Except when they need to get groceries or run an errand across town at the end of a workday. Except ad nauseam. You still have to own a car to make life in alaska livable in the…

Why are you coming at me like I'm suggesting we ban cars

I wonder about the larger context here, though. No matter what academic studies discover or examine, the rise of anti-intellectual culture suggests that we as a species are going to need to pivot to documentary efforts, in a hope that what we learn in isolation now survives to be acted on in a future, more exploratory, generation.

We could also try to fix the anti-intellectual culture instead of just griping about it and/or retreating. It didn't emerge out of thin air, it emerged as a reaction to a mostly-accurate sense among non-intellectuals (i.e., the people who make most of the world actually work) of being constantly condescended to by the intellectual class. What we need isn't to go all prepper for some kind of dark age, what we need is…

What you suggest is worthwhile. But it shouldn't be our only card. Let's do both.

> When you let off the brake pedal, the pressure is removed, but there’s not a “retraction” of any kind. So there’s no pressure but nothing is actually making that gap. The wobble pushes the pads back in, right?

A healthy disc shouldn’t wobble enough to push much of anything. We’re talking like 1/20th of a millimeter.

Should be enough to relieve the pads I think? The less wobble the less the pistons need to retract too.

I mean you can hear scratching when the pistons get crusty and the don't retract like they are supposed to.

Not gonna happen with lobbyists and shareholder corps benefitting from an intellectually stunted populace. The unregulated economic system incentivizes this.

Case in point. Go out and meet some of these people and then report back.

You know nothing about me or where I come from. You're not making the point you think you are.

You can lead a horse to water. It's not my job to encourage intellectual rigor. It's political leadership's. Pushing that burden onto imaginary everyday philosophers you've conjured up is futile.

Said "imaginary everyday philosophers" created the anti-intellectual backlash by, among other things, saying things like what you're saying here. Asking them to either shut up or actually make an effort to bridge the divide isn't futile, it's our only hope.

It’s also the reward of increased regulations on tailpipe emissions. We now have a new target to clean up. It’s not as if this is new, it just used to be we had lead fuel, poorly burned fuel, tire dust, asbestos in brakes, and many other problematic forms of pollution. We’re just going down the list. Also, what you’re looking at is an overweighted responsibility on people/consumers to own the solutions to pollution.…

> No matter what car you buy today it is emitting less pollution than ten, twenty, and especially thirty to fifty years ago. Sure, but a single bus would emit way less than the 60-150 cars (yes, large buses here have a total capacity of about 150 people [1]) it replaces. And if you have a bikable city like about every city in the Netherlands is, there's zero emissions. > Meanwhile we still burn bunker oil (the leftov…

... but not in the desired direction. Sulfur dioxide emissions from shipping appear to have actually been slowing (!!) global warming by seeding clouds which reflected sunlight.

Regen braking uses magnets and takes place inside an encased and oil-cooled motor which should eliminate airborne debris.

Rubber still wears off tires though so that may be worse or not for heavier vehicles

Because there is less extreme (and earlier) braking and less weight shift (drive motors on the rear or all), regenerative braking should lead to less overall tire degradation than comparable friction brakes for even a significantly increased weight.

Though this is contraindicated by Tesla drivers in the extreme Regen mode that induce motion sickness in their passengers and / or are replacing their tires very often (though conflated with rapid acceleration)
