It can be helpful if you do but I see most drivers do not. For example you may have noticed after I used this station I can see many people having trouble with it. If I am doing one of my road trips I check plugshare as well as the network operators app to see if I might have to make alternate plans. Not common to be filled yet in Colorado but if they are you can see when they expect to leave or perhaps even message them depending on your desparation level. We have a row of chargepoints at my office which do sometimes fill, we have a chat group most of us are in to help negotiate. Generally I would prefer the PHEVs move as they should have filled fairly quickly.
