I mean if you really think about it china already has or is on the verge of: - energy independence - ASML level microchip production - the SOTA of AI - citizens that accept surveilence and lack of privacy - strong local manufacturing - eastern world support - yuan recognized as a stable world currency But they do suffer from issues as well: - Aging population - Autocracy (or well, one party system) - Brain drain (bet…

How much more surveillance and lack of privacy is there than the US? The US also has - surveilled cities and less dense places through doorbell cams - surveilled digital communications - social credit scores (try getting a bank account if you've opted out of things like lexisnexis etc)

What does lexisnexis do you can opt out of?

99.9% of use cases of EVs can charge at home/work/shop, don't need separate infrastructure, logistics and supply chains for delivery of electricity. There is a very small fraction of EV trips that need charging on the go. The vast majority of trips are under 3 (or 5 miles).

> 99.9% of use cases of EVs can charge at home/work/shop This is yet again a very US-centric view where you assume people are living in house with a garage.

> This is yet again a very US-centric view where you assume people are living in house with a garage. It is a US-centric view to think that the rest of the world is hunter gatherer tribes. Most people live in some kind of constructed building which has electricity, indoor plumbing, a place to park a car. Before that building is built, the first infrastructure that is ready is electrical, without which most of the tools required for building a home do not work.

A garage is not a sine qua non for EV charging. A place to park is. If a person is buying a car, they would've already figured out a place to park. That place is right next to a building with electricity unless you are sleeping in the woods.

I don't understand why people think that running a cable (a few feet) from the nearest building to a car is impossible.

In NYC that would be the street. The great conundrum of ev's. People that have access to home-charging, worry about range. The one's that mostly sit idling in traffic, don't have access to charging.

The ‘burbs truly are the worst of all worlds. Some of the homes in my neighbourhood have 2 cars in the driveway and another two on the street. They all move regularly. Walkability is terrible. Public transit is iffy. People have to get places on time.

Zoning changes: can't park inside, in front of the house, and on the street. This will address the problems you raised. Unlikely it will be passed.

"home" can be substituted for "place where car resides when owner is at home" without meaningfully changing the point

I like how you think, cars are mostly idling in traffic, we can consider them as stationary, and charge cars while they idle!

Paying the fair share for road maintenance isn't a human rights issue.

The issue is not paying our fair share, the issue is paying more than we would if we drove gas vehicles. They assume we drove X miles (I’m in Washington state) and that is not even close to what I actually drive (it’s much less, I could game it if I drove more than the C miles they compute the fee on, but I don’t need to drive that much).

> paying more than we would if we drove gas vehicles

The 6 people driving EVs in Alberta/Saskatchewan are paying more than $7 trillion in taxes[1]? I find that hard to believe!

Sorry, but I think you're wrong on your concern: in China they specifically fix this issue with buffer batteries. From grid perspective, charging is no different than with regular, slow charging stations. You can still limit their capacity (as in cars that can be charged per 24h), the difference here is you can charge quickly. This is a good compromise for the time being while the grid catches up with demand.

Batteries only help with peak loads, they also cost money and wear out. Let's do some math - a 10 car 500kW charger, with a ~30% occupancy, would draw a constant 1500kW from the grid, if we calculate 3kW average for a household(which is high), that would be the equivalent of 500 households.

I don't think this speculation is needed here, what I described is literally how these super fast BYD/Xiaomi own chargers work in China.

The fundamental problem of high-wattage charges (say 500kW), isn't to deliver power from the charger to the car, but that there needs to be crazy amounts of grid capacity to support them. A house has like 10kW peak sustained power consumption (an apt even less), which it rarely reaches, so a park of these fast chargers need the same infrastructure as a small town. These loads are so huge Cities like Beijing have stro…

In the Netherlands the energy network is undergoing a huge upgrade because of wind and solar- technologies nobody predicted in the 1970s. Things used to be simple: big power station makes energy and lines transport it to every home. Now you have vast wind farms far out on the North Sea and millions of buildings have solar panels. And to top it all off electricity replaces gas for heating and cooking. We're gonna need…

At least they're upgrading your network, over here in Australia they've realized (about 20 years after we became one of the biggest users of household solar) that too many people having solar makes the grid unstable and the load unreliable, so they want to start charging solar owners for feeding into the grid instead.

Most states and provinces I think have already applied a flat yearly registration fee surcharge to make up for lost gas tax revenue.

Most states and provinces I think have already applied a flat yearly registration fee surcharge to make up for lost gas tax revenue Indeed. No one is contesting that. So what is your point? In as you are leveling some sort of complaint against a flat tax, are you attempting to claim that any tax is unfair? If so, why? Let's look at Alberta: https://www.alberta.ca/electric-vehicle-tax-claims Here, it states the yearly…

It will be unfair one way or the other. Washington state has a high gas tax by American standards (60 cents a gallon) but I only drive around 30 miles per week. I would need one tank of gas a month on my previous ICE car, and the gas tank took 13 gallons, so I was paying around $100/year in gas taxes. I pay $250/year surcharge for having an EV, so I’m definitely paying more (my EV is a compact rather than a sub-compact I had before, so I would lose some mileage there, although not enough to make such a huge difference).

I get it though, other people pay less. It really should be by mileage and weight, but privacy advocates blow a gasket when someone proposed to track vehicle mileage either in real-time or through yearly odometer gauge checks.

Charging stations don't need all the environmental equipment that gas stations have to catch oil and gas run off. I guess we could convert old gas stations that don’t need extensive environmental cleanup, but building new ones just to charge EVs is huge overkill when you just need some space in a parking lot.

That's a good point. Charging stations benefit from being a service station too though, with amenities and a cafe etc, since people want something to do while they charge. So a gas station is a better candidate than a parking lot when decisions are made for where to place the new charging infrastructure. Lots of other factors too of course.

I prefer grocery stores because I can run in and grab something quickly. The only problem is that charging is often too quick to do any real shopping, so a smaller convenience store makes sense also.

Parking is not assigned, sometimes you got to drive around for 20 minutes to find a spot to park over-night and its not guaranteed to be next to a street light. By idling in traffic, I meant that we would love ev's since most of the time we are just wasting gas and fuming up our own neighborhoods.
