There is just waaaay fewer planes than cars, but when an accident does happen it is on much larger scale
Yes, EV fires are more difficult to control, but that overall doesn't matter as much if it isn't happening in a building. Also overall EV's tend to not enflame/blow up directly after an accident, giving occupants time to safely exit.
Then it depends on design how easy and cheap it is to replace
More and more it looks like batteries (>70% of capacity left) will outlast the cars lifetime, thus no real need for easy access to replace it.
in normal car you can recharge or change battery at home without any special skills and you can refill the tank anytime instantly.
I don't really see why this follows changing an EV battery. The comparison is replacing the engine, not the small onboard battery (which EV's also generally still have).
With more EVs the demand for elecricity logically increases and it will get covered by easy to build and maintain powerplants that can work 24/7 - coal or phosil fuels power plants
EV's should add around 10-15% to the current electricity demand. It won't come from coal or fossil fuel plants, mostly from renewables, which could have a good synergy with EV's if done right.
but the volume released into the atmosphere will be the same.
That is already incorrect seeing my other answer, but also cars are generally less efficient than powerplants, so you'd still see a reduction in air pollution.
Not to mention most countries in europe dont have the energy grid capacity to cover this inceasing demand yet
They do, or at least they should unless they are completely ignoring grid maintenance. The extra demand isn't that big as I said and it grows overtime, it isn't like you just flip a switch. People also could use renewable from home (solar panels) or work/local (solar panels and wind turbines), decreasing the pressure on the grid if v2g/h is also used.
Lastly we used to be able to change batteries in our phones, then this choice was taken away from us, not thanks to EU it may be coming back, but this western trend of not fixing broken stuff or being able to get only certain parts, just having to buy a brand new product is what is what makes EVs not ecologic choice
This argument can just as well be used for regular combustion engine cars.
There are people who have the same working and safe car for 40 years in the eastern europe
Could be, but likely with a lot of maintenance costs along the way. That or something is really different from eastern Europe and the rest of the world in terms of cars.
more people than I thought are getting new car every 2 years, thats so much material mined and emissions created just by the production
I doubt there are many people that do this. And these cars don't just immediately get scrapped they are sold 2nd, which then in the end will push the oldest cars out of circulation down the line. Also EV batteries can and will be recycled, it is too lucrative to not do that. So the effort/energy used during mining isn't just going to waste.
We need to change people's and companies' behaviour first before EVs can be considered a "green" choice.
This doesn't have something to do with EV's specifically, rather cars as a whole.
they need to stop thinking only of Fukushima and Cherbobyl and consider the hundreds of perfectly safe plants, so that it is affordable and reasonable for people to get EVs and get their full use out of them
Even if the German government drops it anti-nuclear stance from ideology, they still wouldn't adopt it for a certain reason: new nuclear powerplants are extremely expensive (per unit energy produced), more so than solar, wind turbines and coal and around the same as gas powerplants. Maybe this changes eventually, but the current financial situation isn't beneficial for new nuclear powerplants.

Nuclear powerplants don't really help with the renewables intermittency, since they best run constantly/as much as possible. Now, you could say nuclear needs to be the baseload and renewables everything above, but if you have more renewables than necessary, the lower generation costs could outperfom the nuclear base load at certain moments, causing them to either produce at a loss or lower output, which isn't really great for nuclear. So the government will always have to guarantee that nuclear reactors get a certain minimum price and production rate, essentially subsidizing nuclear in the long term even when renewables don't need subsidies anymore and are cheaper.
The main danger I see is now going full into nuclear only to find out that by the time most of these plants become operational, storage is so much more viable that it starts to compete with these plants, meaning you might be stuck with more expensive plants for 60 years even when you have better alternatives.
And now you can say that storage isn't going to become viable that soon, but remember that solar panels were 10 times more expensives around 10-15 years ago and that the price mostly went down due to economies of scale. Storage wasn't really needed that urgently in the past, so it only is coming up now, it is very possible that they'll make a similar growth rate in the next 10-15 years in cost as solar panels had.

Battery storage using standard lithium ion batteries is quite expensive at the moment;
That is indeed true, however even without improvements in battery tech it is expected that Li-ion batteries will become cost effective around 2030-35 just due to scaling. However I don't think Li-ion is going to be used for the grid past quick reactionary means to stabilise the grid, I'd expect other battery chemistries to full fill that role in the future ('rust' batteries, iron batteries, flow batteries, ...) as well as completely different storage solutions (CAES, LAES, heat energy storage, ...).
The market for large scale grid storage is rather new, so the companies and technologies catering to it are too, they now need some time to prove their products viability and to scale up. By 2030 the gridstorage situation can look completely differently. And even if we decide to build new nuclear powerplants now, they likely wouldn't start operating for another 10-15 years, so a similar timeline to what storage might need.
These current energy shortages in Europe speak to that.
Yes and no. Yes, renewables have underperformed this year (mostly wind, solar was overall still pretty stable, though not favorable), however the greatest problem is the gas supply which has been seriously hampered causing the vast increase in prices. And even nuclear wasn't a guarantee for the UK, where there was an unforseen shutdown for some reactors. Essentially this is a perfect bad situation.
Grid storage would have definitely helped though.

@canemcave Sanctions were announced, however the German government quickly took the necessary actions to remedy the situation (though it was more of a temporary stopgap, essentially justifying to the German court that the German/EU decision was in line with German law). The Polish government on the other hand is using it to fuel an anti-EU stance. That is the difference. Moreover if this Polish court decision is followed, the only way forward is for a complete renegotiating of the EU treaties or Poland leaving the EU. A complete renegotiating isn't possible, not in the least because one of the things the court attacked are fundamental EU values. Thus the Polish government has essentially 2 possibilities to move forward: change Polish law to be in line with the treaty or leave. Currently it is doing neither. Why? Because neither is a good option for them. If they change Polish law it will be looked at as them backing down. If they start the process to leave, they'll quickly be chased out of office by the 80%+ of poles that want to remain in the EU.
By essentially remaining in limbo for now the Polish government hopes that the EU will eventually back down first. The EU can't back down, there is no way, it would be the end of the EU. Thus Polish government chooses limbo, giving the EU no other choice but to slap with (budgetary) sanctions, since it neither can push Poland out, nor do any more decisive sanctions with Hungary blocking every effort.

@gilian2587 No, we are not 70 years away. Firstly there are several storage solutions coming up, ranging from different kinds of battery technologies to storage using temperature differentials and highly isolated storage tanks.
Even if we ignore this, research already estimated that lithium batteries would drop in price enough by 2030-35 to be a competitive gridstorage option, purely due to the scalegrowth of Li-ion batteries, ignoring possible technological improvements in the chemistry.
Also you'll only have an overabundance of energy with nuclear if you build and overabundance. With the same kind of thinking we also could get an overabundance with renewables, considering solar could power the world by covering only a relatively small part of the sahara with solar panels. With 2019 production of solar panels (not the electricity generation the actual production of new panels) and placing them in the sahara, we could produce enough to power the whole world within 15 years from now (though I think this is only for current electricity use, possibly not added needed production for things like EV's, heating, ...).
