I would like to know more of the "Parking" charges. You might be interested in the following: -
Parking Meaning in Law - To leave a vehicle in a carpark or other reserved space” and “To leave in a suitable place until required.” The concept of parking, as opposed to stopping, is that of leaving a car for some duration of time beyond that needed for getting in or out of it, loading or unloading it, and perhaps coping with some vicissitude.
My read of this is that you stop at at charging bay you do not park. Afterall you wouldn't expect to drive onto a petrol station and face a parking charge when filling up. This likewise is not parking but stopping. As you are stopping and not parking, what reason do you have for looking at parking notices when they are not relevant. What is also rather gaulling is that in this instance the land owner, for some consideration, transferred these parking bays to Tesla to become charging bays. Having sold them they are still trying to charge for them as if they still owned them and as if they were parking bays. Clearly they are not and under English law I believe it is illegal to park in a charging bay you need to use the bay to charge. Once it is a charging bay it cannot be a parking bay. So long as you are charging I cannot see how you can be alleged to be parking. Additionally under the law, the land owner has to be give people entering the space, time to consider any regulations. In this instance not only does there not appear to be any signs relating to stopping their parking terms kick in after 0 hours and 0 minutes. I believe the parking signs refer to Holiday Inn parking. If you are in a Tesla bay are you not on their property, would you think you were on someone else's property? Surely any conditions as regards the Tesla charging bay need to be set out by Tesla according to the normal regulations including clearly stating a quantifiable penalty. If it is Tesla's intent that customers should be fined for using their charging bays then clearly they should say. If not then I think it beholden on Tesla to ensure that their customers are not screwed over by the land owner they contracted with to create the charging station. Tesla seem to dismiss matters saying this is a private land issue. This is not strictly accurate this is an issue about their charging bays which they have acquired by some contract. The site comprises land either owned or subject to conditions Tesla has agreed and separately the Holiday Inn car park and hotel. Do you know from any signage who's site you are on? As regards any need for registering registration details at the site are these not provided the moment you connect your car to the super charger. It amazes me that if the intent was never to charge charger users that Tesla allows their customers to be fined for using THEIR site.
