The infrastructure one shouldn't be static either. I'm not fast charging an electric car to ride my non-electric bicycle, I'm not the reason the grid needs expensive upgrades so much...

It's being metered too now. In Belgium it's calculated on your max peak usage per month, averaged out over 12 months. You fastcharge 2 cars at once while running a washing machine, electric heater, vacuum, a bitcoinmine etc all at once: your infrastructure part of the bill rises. The only stupidness is that they put the "fictional minimum capacity used" too high, so you don't benefit from practically 0 capacity usage.
