Not to mention the fact that large portions of the United States are undergoing rolling blackouts right now No, they're not.

Right. You're equating storm damage and armed attacks on infrastructure to insufficient capacity in general.

The truth about my EV? In summer it gets me to work, and back, without me overheating. In winter it gets me to work, and back, without me freezing my ass off.

The later is something my Diesel never could manage, taking about 20 miles to get temperatures above the freezing point. While my EV is nice and cozy after about half a mile.

> But you know what I don't do? Freeze my ass off standing in a gas station in subzero temperatures and howling winds! Not missing that at all. Right! And I suspect by 2035, not having a 220v outlet in the garage will be like not having a microwave in your kitchen in the mid 90's.

Not everybody has a garage. Cities are full of parked cars in front of residential buildings. It did park my car in a street when I was living in a city. By 2035 those streets must be refitted with chargers, one per parking slot and somehow replace the energy distributed as gasoline and diesel with electrical energy. If that doesn't happen people will have to leave their car at a charging station for far more time th…

In Finland we have 220v outlets at every parking spot, since the batteries of ICEs just die during the -20C winter nights without being hooked up.

We all charge our EVs on those same outlets, and I never heard of anybody not having a full charge the next morning.

The main reason why we have so many EVs here -> they are more reliable in the cold. People stopped freezing to death in their Diesels that got stranded on the roadside.

In a little under half the US. We get at least a couple days a year where the wind-chill brings the temp below -40F with a thermometer temp of -5 or less as a high for the day. My gas car hasn't been happy about starting the last week. Two years ago, I was working 2nd shift and only had the diesel truck. Got to work fine, got off at 2 PM and even with winter blend and a bottle of Heat in the tank, the fuel gelled and…

The original commenter was stating that EVs were entirely unsuitable for a hypothetical person. The only way that it I can envisage it being entirely unsuitable is if they had no access to grid electricity. My comme…

Everyone doesn't have a garage. If your infrastructure has the chargers on the street, we're back to the original issue where they don't charge well in the cold.

Eh. I’ve found with modern cars they can still start at -30f just fine. At least, mine can. My first car? I had to constantly give it gas for a while even once it started. People gave me funny looks when I was essentially revving my engine like I was showing off in my ‘88 Grand Marquis at stop signs in the year 2005.

Eh? A gasoline powered car will struggle in the cold because: - the battery used to spin the engine is going to have less capacity in the cold - the engine oil is thicker and requiring more energy to spin the engine - gasoline won't atomize as well when it's being sprayed into a cold environment (this is why your engine runs richer right after a cold start) A diesel powered car will struggle because: - the temperatur…

I don't disagree, but I can only tell you my experience. My car (a freakin' Camaro that I drive year round) has yet to fail to start, and it's 11 years old at this point too. The radio doesn't work when it's below 10 degrees though, so that's fun.

> not having a 220v outlet in the garage will be like not having a microwave What about the millions of people who live in apartments and rowhouses?

I have a charger in my uncovered townhouse spot. It’s really not a big deal. Nowhere near what you and other commenters here are making it out to be.

My HOA woulndn't allow that in our common parking area.

If the "guess-o-meter" is so bad that it leads reasonable people to wildly wrong conclusions, I'm hesitant to blame that on the user. If all the factors you described are understood by humans, why aren't they factored into the display algorithm? If the car is going to drain battery for an hour getting warm before it can start to charge, then say that on the display.

The car can't predict the severity of weather, whether or not your going to preheat the car or your driving style. All of these factors combine to make the range estimator a guesstimate on both gas and electric cars.

But it could make a better guess than it does, or even leave the numerical guess untouched but give the driver other useful information. Specifically, the information you gave in your first comment.

Teslas have great big dashboard screens. There was no need to leave OP thinking that the car was unchargable unless it was brought into a warm place.

Do you use your car 24/7? No, you don’t. Nobody does. And if you did, there are charging systems outside of home charging. Did you miss scheduled defrosting, where the car does it automatically so it’s ready in the morning? Does your car even have the ability to do that without you in the car? I didn’t think so. Be realistic about what is a pain and what isn’t. None of your rebuttals are much of anything except “woe…

> Do you use your car 24/7

Yes, we need it reliable: always available in case of need.

> take out an app

I do not see any chance of ever using a car that requires a smartphone.

The HN system just refused an edit, I will have to reply instead:

I am reading the words of former NATO supreme allied commander James Stavridis,

> Every year, the number of devices connected to the internet grows rapidly. By some estimates, the count is up to more than 50 billion devices, from around 7 million a decade ago. The benefits are real and obvious. (Hooray, I can close my garage door from a thousand miles away on my household Nest!) But so is the fact that each of those devices is a unique point of attack for hackers. We have created a vast, undefendable threat surface

You simply do not put unrequired attack surfaces on critical devices - it is cretinous -, and you do not encourage the practice - it is criminal.
