Combustion engine is a perfected tech, which can easily last 100K+ miles. EVs do have a cooling system for the battery.

EVs also have a battery which can be $20k, and electric motors which are $10k. This really makes them awful on the used market when the warranty runs out. If a used Model 3 needs a battery it is basically scrap.

but a used Model 3 doesn't! and that's the fake news here. These batteries last ages. https://www.youtube.com/watch?v=doAcNVuTnXU

Seriously, a YouTube video is supposed to be proof that batteries last ages? What is ages? If you provide something I can read you might have been able to change my mind.

Truth is not many want to risk buying a used electric car and the depreciation reflects that.

Generally, 10-20 years and 100K-200K miles. The US requires a warranty of 8 years and 100K miles.

For newer cars it's hard to tell for sure since the tech has improved significantly in recent years. But even the earlier cars have done better than people expected.

A quick google turns up lots of sources you can read. Here are a few:

Battery costs keep coming down. We are now sub $100/kWh, and Chinese batteries are approaching $50/kWh. So a 75 kWh battery will cost less than $4000 in the not too distant future. And costs should be way more interesting when you have to replace your battery in 2040.
