I have just ordered my new car, a PHEV, I have noticed when we go to our local Aldi supermarket where there are two charging bays next to the disabled parking bays, that there often cars parked in the two bays that are not charging them, they look for the most of the time that these cars are ordinary diesel or petrol cars. The problem is these bays are the nearest to the supermarket entrance apart from the disabled bays, and most motorists wont use these.
They are probably staff cars, we have the same at our local Tesco a Outlander PHEV plugged in all day virtually every day, the EV charger flashing full the majority of the day, it just a fact of life.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
