I guess that’s a rhetorical question? Because clearly many people do actually prefer a BMW to a geo metro, despite the price difference.

This kind of strategy ignores second order effects. For example, by buying a gas guzzler and not using it much you might lower the emissions from that specific vehicle. But supply and demand rears its ugly head: you're contributing to the increase of similar gas guzzlers' value in the market, which means that other people are more likely to maintain those vehicles in working order and resell them, instead of scrappin…

We need to get used to using the term 'power consumer' instead of emotive terms like 'gas guzzler' to describe IC engines. Currently coal powered BEVs are considered by some to have superior efficiencies to gasoline powered vehicles.

I would expect that to be true. Not the best numbers, but Wikipedia puts coal power plants at 37% efficiency and combustion engines at 20-35%. This makes sense too, power plants have space, money, and an incentive to increase efficiency. And in reality, no power mix is 100% coal, increasing the overall efficiency to above 37%.

Plug in electric hybrids strike me as insanely complex machines compared to Ev's. It strikes me as highly unlikely that from an environmental standpoint our (societies) time is better spent building them, than it is spent increasing the rate at which we can build batteries.

I'd expect EVs to be cheaper if they are actually simpler, last time I looked that wasn't really the case outside of cars produced in China that most western customers wouldn't buy.

You can get a Bolt for around $11k after incentives. OK the incentives part is a wrench in the equation to be sure, so it may be hard to answer my question…

Are you saying hybrids cost less than that?

Look at the other side of this: by buying an EV, you're increasing the demand and increasing the cost barrier to owning one, so people are more likely to buy a cheaper, gas car. An EV you're not going to use much that sits in your garage is one less on the market to drive the supply up.

Generally, the idea that people toss their cars in the garbage is wrong. They enter the secondary market and someone drives them either way. Scrapping them only happens when their useful lifespan is over.

Buying a newly made gas guzzler is a different story.

To further develop the idea of letting EVs go to people who will drive them the most, the true bottleneck is batteries . So, the problem is to get batteries on the road in a way that they will displace the most gas miles as soon as possible. This suggests a far more effective strategy of first replacing the fleet with plug-in hybrids (PHEVs), then in a second stage, replace those with full EVs. For most city vehicles…

The Chevy Volt was pretty sporty (damn the suits who killed it), and

Well there's your problem. The fact that EVs are toys is making you think PHEVs are also toys. There are PHEVs currently on the market that can compete with the Ford Focus and the Honda Accord.

> For most city vehicles, a PHEV will electrify the majority of the miles with a fraction of the battery capacity. There have been studies on how PHEVs are used in the real world and this is just not what's happening, see e.g.: https://theicct.org/publications/phev-real-world-usage-sept2...

You can also fully charge a 10kWh battery overnight on a 120V charger.

Exactly, it induces demand. Same went for efforts to reintroduce ivory in a more ethically sourced way back onto the market. Demand exploded and kick started poaching again. There are other examples too.

As for buying coalmines, typically mining rights are sold to miners as licenses that owners expect to get a percentage from. When the buyer turns out to be an environmental NGO the license gets revoked pretty quickly. This happened in the US earlier this year. These strategies will often run into implementation complexities.

A different way to get to the same result as a minimum fuel requirement would be to raise base prices and offer steep bulk discounts. This would be easier to enforce than a minimum fuel requirement. Unfortunately it might raise "price gouging" complaints.

Exactly, I don't get how that would increase throughput.

It's not about increasing throughout, it's about increasing user satisfaction. A system where 60 customers are served an hour, and none of them has queued, is theoretically better than one where the same amount are served, but each has queued for 10 boring minutes. You achieve this by disincentivising queueing.

Those who really want your product now have to mob up outside your stall and hope they're the next lucky random fucker. They're still waiting.

Those who don't really want your product don't wait in a line for it anyways - the length of the line itself is a natural filter for availability of the good.

Basically - has satisfaction actually gone up if those who would be extremely satisfied by your product no longer receive it, and random folks who may or may not want your product do? I'd bet money the answer is a solid "NO".

There’s an extremely obvious difference in 0-60 times between a Prius and a Model 3, and that matters on an on-ramp. (Replace 0-60 with 5-60 or 25-60 or whatever you measure of acceleration you prefer).

Is it necessary? No, obviously, people aren’t dying left and right trying to merge in Priuses. It is very noticeable, however.
