If you live in North America and have a house or townhouse get a Tesla. It is such a no brainer. $5 for 500km vs $100 for 500km (gas) is just too good

Or, y'know...get literally any other EV. One that doesn't support a neo-Nazi trying to wreck America's economy and political system for his own gains. I hear the Hyundai Ioniq is supposed to be pretty good.

Try both. Report back. You people read too much news. Never the source.

We're still burning massive amounts of fossil fuels as waste products from refining oil to make plastics and chemical feedstocks. A huge amount of that is propane that just gets flared off. We could have been running cars on that for decades, but getting people to make their dirty polluting inefficient old petrol cars run on fuel that emits carbon dioxide and water with no HC, CO, SOx, NOx, or particulates was nowher…

Compressed propane is explosive, more so than liquid gasoline or batteries. Though batteries do burn hot and are hard to extinguish.

Actually it's considerably less explosive than petrol and far safer in a crash.

If a petrol-fuelled car goes on fire, the fuel tank will explode. The tanks are usually thin plastic and will split open in an accident, spilling fuel everywhere.

By contrast, the LPG tanks are pretty much indestructible and if you remove a tank from a car that's been on fire (a lot of taxis are LPG-powered and seem to go on fire late at night for some reason, especially if they're parked in the wrong part of town) you'll find the tank is still about as full as it was before the car got burnt.

Does the study account for things like coal-fired power plants in Delta, Utah being operated by Los Angeles Department of Water and Power? This makes for less pollution at the site of the vehicle, and more pollution two giant western states away.

Yes, studies account for worst case coal power production. The pollution controls at a power plant are significantly more effective than the on-vehicle pollution controls for a gasoline engine.

What do you think refineries are doing

The number of ICE cars I get stuck behind from time to time that just REEK is amazing. I’m in a decently well off area too. Some putting off soot clouds, white smoke, nothing visible but clearly not doing complete combustion. Sometimes I wonder if half the cylinders are even working. I’ve heard one car like that is the equivalent of a surprisingly large number of modern ICE cars is in good shape. I love EVs. I’ve had…

Speaking of smells.... One good thing about driving an EV is that weird oil or hot coolant smells are from someone else's car (and not a problem with your car) (although yes technically many EVs have coolant loops)

As an aside, I'd like to mention that like 9 times out of 10 if you are driving down the road in an ICE vehicle and smell weird oil or hot coolant smells you are smelling someone else's car. The wind blows away a lot of your own stink before it gets to you. I learned to ignore anything that didn't smell 1) when I was stopped, and 2) more than once in totally different locations. After trying to track down smells that I thought were mine and were invariably from someone else nearby.

No, it's based on measurements in California where in-state coal is negligible (something like .1% of our total electricity). A power plan in Utah would only show up if the pollutants wafted their way across state lines

Ok, but tire pollution is still a problem: https://grist.org/transportation/electric-vehicles-are-a-cli... https://caltrout.org/news/did-you-know-your-cars-tires-could...

True. But there are 2 ways to read this: 1: Yes, let's stick with ICE cars and die of preventable illnesses because EVs are only a massive improvement, rather than absolute perfection 2: Hey let's take this massive improvement and enjoy enormously cleaner air I meet way too many people from group 1 unfortunately.

That's exactly what I wrote: "it's a step up".

The Tesla Model S has been out for almost 13 years, so you can already see it. Your phone doesn't have liquid cooling temp management and is probably recharged daily. With a car that has 300 miles range, a lot of people probably only do a full cycle every week.

It was recently in the media that old Tesla’s are now worthless once the batteries are dead and that this is happening now. Heres one such source but theres hundreds if you care to look: https://min.news/en/auto/2a2636e0ac962b5d94ee68babcd09a3d.ht...

> are now worthless once the batteries are dead

13 years old dead luxury cars are worthless, yes, especially when the tech is quickly evolving. That doesn't say anything about how long it takes for them to die or how reliable the tech is.

You're not allowed to drive cars like that in a functional society. When you go for your compulsory car checkup it wouldn't pass the required safety standards.

I think the point they're making is that the ICE cars that OP is complaining about also aren't supposed to be driven in a functional society. The difference is that mostly wealthy people can afford EVs: https://ampo.org/electric-vehicles-are-out-of-reach-for-most... thus they stay maintained and have a polished image.

I think they are more accessible now than when that article was written. My wife and I bought a mid-trim Hyundai Kona Electric for under $35,000. Besides, lots of people buy used cars, and there are crazy deals on used EVs. I've seen Bolts go for under $15,000. 2 year old ID.4s are selling for under $20,000 in my area. You may not find a $5,000 beater, but EVs are penetrating further into the middle of the market now.

There are also lower ongoing costs for maintenance and fuel.

There is still the secondary wealth filter of having a place to park and charge, of course.

And even those those ancient luxury cars can often be repaired by a third-party shop like EVClinic.

There aren't many 10+ year old EVs yet, and demand is limited. This is changing, and EVClinic will be the first of many aftermarket EV repair shops.
