The UK government is now under pressure to introduce official road signs indicating the presence of electric vehicle charging points. Would this help in your area?
Why invest in EVs and charging stations and then not tell people where they are? Crazy
Believe me owners of electric vehicles KNOW where charging stations that are relevant to their situation exist.
EV owners, as a group, are probably the most knowledgeable individuals in transportation. Most are enthusiasts and keep aware of every new item or service that has or may have an effect on their choice of travel.
