Yes, because an electric parking meter uses only a few watts of electricity and may not even be connected to the grid (the most common ones I've seen just have a tiny solar panel). A electric vehicle charger may use 200 kW and require its own dedicated transformer. A fast charger is a fairly substantial cabinet. Now you're jackhammering the sidewalk to bring an underground electrical service to that spot.

Can you apply your thinking to petrol stations. We build floating city's to extract oil thousands of meters down. Is running some cables harder then that?

An off shore oil well will basically extract black gold, paying for themselves in no time(at least when the oil barrel price was high). Electrical charging station on the sidewalk not so much.
