Not that there aren't any problems, and there are definitely "dead zones" so to speak, but the situation you're describing isn't valid everywhere.
I live in Austria now and charging infrastructure is still very sparse in the city where people keep their cars parked and there's no signs of new chargers being built so I'm also skeptical on meeting the deadline.
Also considerig that most people have old beaters, those people won't be able to magically afford more expensive EVs with worse range.
So I think your parent is right and your situation in Benelux and the Nordics is the exception not the norm. If the infrastructure doesn't massively improve across the block and the price of EVs doesn't tank along with a range increase, there will be uproar in the less fortunate EU countries who depends on ICEs and the ICE deadline will have to be postponed again.
You clearly don't know my city leadership/country. Stuff only starts to move after the shit has already hit the fan and everyone ahs their pitchforks out.
I don't doubt we will get there eventually, but they will not be able to stop selling ICE cars by 2035; about 5 years from now there will be an uproar and the deadline will be pushed by at least another decade. The technology is getting better, the prices are getting lower, but infrastructure is nowhere near ready.
