Yes, they should function like gas stations and be regulated similarly. When I approach a gas station, I see the prices usually on large signs. If not, I always see the price I am actually paying displayed on a screen. None of these things are true for an EV charging station, which I think should be regulated.

Cheaper prices with subscriptions are not a problem at all. It's just that I should always see the final price that I will be paying per kWh before starting to charge.

On a related note, there is already a plug-and-charge system that identifies the car when it gets plugged in and is capable of charging the owner, but it almost never works. This is also something that should be mandated for larger EV adoption.
