Not possible where I live, not enough public transport, not enough bike lanes and too far to travel Daily

Bikes sound like a great idea until you decide to live in the hills/mountains, or a place where it rains/snows often, or you need to buy more than 4 bags of groceries, or you live in a desert, or you are moving furniture.

Please tell me more about how easy it is to move furniture with a VW Polo!

One thing that would go a long way in helping with that would be if we improved the quality of urban schools / parks to the point where fewer people felt like they had to move to the suburbs to start families.

I don't understand how hydrogen didn't win the race. Transports and explodes just like gasoline. Make car go fast. Doesn't degrade like lithium. Can be "mined" by throwing electricity at water during times of excess generation by renewables. When you burn it, it turns into water. Has none of the national security concerns of distribution of lithium mining and production in other countries.

You need green energy to produce climate friendly hydrogen. This is a LOT more inefficient than to just use that green energy directly in EVs. Thus green hydrogen is also expensive and most importantly it is needed in the industry. It's the same with e-fuels.

Hydrogen currently doesn't produce, store or transport well. This means it is not as economical as gasoline.

Not really a fan of lithium batts either. We're going to end up with some environmental problems down the line but its the most economically viable tech we have at present if we're intending on living the way we currently live.

As I understand it, the big issue is energy density? A tank of gasoline takes you quite far compared to an equivalent tank of hydrogen.

And don't get me wrong, lithium batteries are super bad at this too, but I do think that has been a limiting factor for H cars.

And then there's the whole tire dust issue which is definitely a conversation worth having.

Because right now we don't have that much excess energy... Therefore it's just a waste of energy to use it, because it is way less efficient. AND on top of it an hydrogen car also needs a battery just a smaller one. So it has all the downsides without any upsides. The only upside is that you can recharge your car faster and it has some more range. But both those things don't matter for the average consumer

Production is wildly inefficient and the storage and transfer of the stuff is quite tricky.
