An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

Boy it sure is easy to win a debate when you use fictional information

I am being serious - can you factually counter those points? I'd like to know the truth of the matter.

I can. Electric car batteries last 10+ years, often longer than the body work of the car. Lookup Lithium Iron Phosphate, this has around 5-10x the cycle life of conventional lithium batteries. Combine this with the complex heating and cooling systems, battery and charging management in modern EVs and you have something that lasts as long or longer than even a diesel engine.

Cell phone batteries die quickly because both their construction and the way they are managed favour capacity, cost, and charging speed over longevity. Car battery design is much more focused on longevity by comparison. They are also cycled more often and more completely than most EVs.

Grid issues are a real problem. Cars can be used to make this worse or better depending on how they are deployed. If they are charged during peak energy production from solar they can actually help rather than hurt the grid.

You can also rapid charge a car in like 30 minutes. You don't need 12 hours.

Thanks, I'm not sure why I was downvoted for asking a legitimate question.

I suspect people just assumed you were the same person who wrote the sarcastic comment before the one you replied to and that you were just being combative

Well.

To fully charge a leaf at a public fast charging station takes an hour. https://www.nissanusa.com/experience-nissan/news-and-events/nissan-leaf-charging-101.html

My up! can get about 260 miles out of its 30ish liter tank. That is about 1/3rd more than a new leaf. Hardly half the distance.

The electric grid will be fine. This is not the first time it's expanded because of new technological demand. And I've never heard of 5 EVs overloading the grid.

And if the person above could read they'd see that all of these are battery problems, something the original comment said we should have put our focus improving on long ago.

Edit: I'll just add that I love my ICE cars as much as the next petrol head, but the future is electric cars for at least daily driving. We've pretty much perfected combustion engines at this point. F1 engines sit around 50% thermal efficiency, and we're not gonna get any meaningful amount above that (but I will be happy if it turns out I'll have to eat my hat in the future). I just hope petrol engines don't become banned in the future for the enthusiasts.

Batteries don’t fail after 5 years, for starters. Source: literally any used car site

No, you see, that's not how it works. The battery needs to be filled to 100%, just like a gas tank. And you should only ever charge once you're under 10-20%, just like a gas tank (it's silly to top up every day, that's just a waste of time). We must be able to exactly replicate the current paradigm for people to be able to adjust.

I drive about 150 miles a week and get gas every couple of weeks. It takes 5 minutes. If I have to go to a charger I'll be there for hours. It's absurd.
