I'd be interested to know who would use these. I can only imagine them being a last resort if the ones in the main car park are all broken or in use. This also raises the question of what happens to the fuel forecourt once there aren't any ICE vehicles on the road. Change it to an EV charging hub would be the obvious answer... but then you've effectively turned it into a services area within a services area!BP are installing their 150kW Rapids on their forecourts. Maybe the Ecotricity exclusivity deal didn’t extend to the filling station part of the MSA. It’s often a reasonable trek to the main building with no dedicated path as usually you stop there to refuel on the way out.
I can see services being remodelled eventually to remove the fuel forecourt, and make it so the main building is accessible to all the car parking/charging.
