EVs have massively less brake wear because most braking is regen, not friction.

No, they don't. They have massively less brake wear than a traditional ICE car. But that's also true of a plug-in hybrid.

Then there is the whole cooling system too. Radiator, fluids, pump. Fuel pump and filter too.

You're right about the fuel filter. It doesn't get changed often, but it does get changed.

But EVs have a massively more complex cooling system than ICE cars, because they have to have coolant flowing through multiple motors on opposite ends of the car and through the battery in addition to the HVAC, and you have a heat pump instead of just a simple radiative heat exchanger. And most people do not ever replace the coolant in their ICE cars.

is there some benefit to watching PBS/hearing NPR off the public airwaves

Yes. We don't have to give the broadband providers and cellular system operators a 'cut of the action'. Even if it is free/subsidized for the public, the aforementioned parties get quite a pile of money from the government*. And now they'll have one less competitor.

*The Universal Service Fund being just one example of a pile of money that never seems to trickle down to the public.

... PC mice only had two buttons (one for a mac). Only those weird UNIX systems had a middle button. For some reason, three button functions became the norm, whether an actual third button or the click function of a scroll wheel. Popular demand in action.

If you want to Ctrl-C, Ctrl-V, go right ahead. Don't like the middle button? Don't use it. I'm not certain, but it seemed to me that this was an OS UI "style". One button on a Mac, two on a Windows machine and three on the various *NIXes. Not per application. Why not keep the default that way?

You aren't factoring in all the other maintenance a fossil needs too. Brakes, fluids, belts, gearbox, exhaust, filters, all sorts of crap.

EVs and hybrids shoudln't have significantly different brake wear. Factored in oil changes, which includes the oil filter. I've never needed to add any other fluids in any car I've owned other than wiper fluid, which an EV also requires. I guess I left out the air filter, but that's such a tiny maintenance cost compared with the other stuff that it almost isn't even worth mentioning.

Belts and transmission do wear out eventually, but that's not an issue unless your car is outside of its warranty period, and an out-of-warranty EV can also have things go wrong. The only straightforward comparison is between two in-warranty cars, because it's impossible to predict the costs for an older vehicle reliably. It might go 300k miles or it might blow a head gasket 10 miles out of warranty.

Add to that an oil change for $100 every 5,000 miles on oil changes

Every... 5,000... miles? Are you out of your mind? Cars didn't need oil changes that frequently even back when they used unleaded gasoline. How far are you willing to go to lie for the petroleum industry?

An oil change for $100? Are you out of your mind? Where are you getting your car serviced?

Jiffy Lube in the Bay Area. And while cars are under warranty, if you don't do an oil change at the recommended interval, it can negatively impact your ability to get engine problems covered under the warranty, so most people do so.

That is all true except PG&E's EV2 plan has off-peak energy at 28.5 cents per kWh, which should cover most of the needs of people who charge at home. That rate makes it competitive with the Prius, even before you consider oil changes.

Of course, they also charge you more for your heat and air during the day. With a whole-home time-of-use plan, they're likely to get their money either way.

I'm pretty sure the only way you're not going to get screwed with your pants on is to have a separate meter on an EV-B rate plan. Totally worth $1.50 a month. Too bad I'm not currently eligible because of where I live (because PG&E doesn't own the meters). Then again, I have unlimited supercharging, so I guess I probably wouldn't use it anyway. :-)

Well, if you can charge from solar the equation changes significantly-- closer to $0.09/kWh or $0.02/mile.

Sure, but only if you also have a Powerwall or similar. Otherwise, your car is going to be at work during the day, rather than charging at home, and you're going to be getting jack s**t for your excess solar during the day thanks to PG&E's rate structure, and then buying that power back at night at full price.

PG&E residential service averages 45.33 cents average per kWh.

That's crazy? California has huge amounts of solar generation, but no cheap mid-day tariffs ?

PG&E nearly went bankrupt with lawsuits over their mishandling of gas pipe maintenance (San Bruno explosion) and high tension line maintenance (multiple wildfires). If they can't make a profit from cutting corners on maintenance, their only choice is to make a profit with extortionate rate hikes. /s

In all seriousness, the biggest mistake multiple California governors have made was not letting PG&E go bankrupt, buying up the assets, and starting over with a state-owned not-for-profit power company. For-profit essential utilities are like for-profit medicine: you pay more for less. Competition never really works when you have a natural monopoly like essential utilities or when comparison shopping is impractical, such as emergency medical care. That's why certain essential services are generally better off socialized. And anybody arguing otherwise doesn't have a solid grasp of economics.

If you cannot charge at home, their cost per mile goes up to the same as a gas car's or more.

In California, even if you can charge at home, the cost per mile is more than many gasoline-powered cars:

Model 3: 3.7 to 4.2 miles per kWh. PG&E residential service averages 45.33 cents average per kWh. That's 10.79 to 12.25 cents per mile.

My usual gas station is $3.90 per gallon. A Prius hybrid gets 56 miles per gallon. That's 6.9 cents per mile. Add to that an oil change for $100 every 5,000 miles on oil changes, which is 2 cents per mile, and the Prius hybrid is still 2 to 4 cents per mile cheaper than the Model 3.

The only way you save money per mile with an EV in California is if you have free unlimited supercharging or free workplace charging. And even then, somebody is paying for your charging, just not you.
