Those numbers don't make any sense. #doubt. Is this counting cars with gas engines or something? Counting hybrids as "EVs" should be severely discouraged.
Hybrids aren't terrible but they should be listed as hybrids, not EVs.

FSD, maybe a sporty performance boost, mobile data for streaming Netflix and whatnot... It's a fantastic business model.

Lol The Chevy Bolt beat the model 3 to market too. How'd that "Tesla killer" work out? Rivian vs cybertruck will be a similar scale of embarrassment.
I honestly don't even mean to trash talk the Bolt or the rivian. But to suggest they're serious competition for Tesla is just out to lunch.
If you invest based on the fact that Elon Musk is a terrible person you're going to suffer.

Absolutely. I don't think it's an especially good option right now but it's not fundamentally bad. It definitely deserves a place in the mix. That niche could grow or shrink in the future depending on how tech develops.

Ok, I was being a bit of a dick there. Sorry.
Hydrogen that is attached to all kinds of things is not usable in an engine or fuel cell.
Since there are no resources of free hydrogen on our planet. we have to produce it by splitting it out of molecules like water (h2o).
We do that using electricity
Now we can use it to turn our wheels, great.
We can do that with a fuel cell or by burning it. The fuel cell is most efficient. It combines the stored hydrogen with oxygen from the atmosphere producing clean water out the tailpipe!
At this stage you're probably seeing the problem. We start with water and end with water. The only energy entering the process is the electricity we used to split the hydrogen from the oxygen in the first step. Without a source of free hydrogen, the process is simply another type of battery to store that original electrical power.
That doesn't mean it's useless. It's a higher density battery than the solid state options or lithium ion batteries. But it's far less energy efficient so it's only likely to find a niche where very large capacity batteries are required.

What? No it isn't.
Where is all this hydrogen??
There are no hydrogen resources on this planet. Wtf are you talking about? We have to make hydrogen by splitting it out of water or methane.
It takes more power to produce hydrogen than we can get back by using it for transport. On earth, hydrogen is a battery, not an energy source. (Out in the solar system there are actual hydrogen resources that could be used as energy sources out there in the future)

Omg ya, it was so bad! Like, missing ceiling tiles with electrical wires hanging down. Lol
I've been through several times this year and it's very nice now!
