Concern about the weight of EVs in car parks is all but complete scaremongering garbage.
The car park not only supports the weight of the cars within it, but also the weight of the structure (walls, floors, access ramps etc etc).
Not only are these several times the weight of the cars they support, they would be designed with a substantial safety margin.
Assume the average car park space is 10 sq m and the deck supporting the car is 300mm thick, the total volume of concrete is 3 cu m. Concrete weighs 2.5 tons per cu m - the weight of just the deck holding the vehicle is 7.5 tons.
Multiply by (say) 3 to cover access, ramps, pedestrian walkways, walls etc gives a structure weight of ~20 tons (20,000kg) per vehicle. Adding (say) an extra 400kg for EVs would increase the load by 2%.
Any building is so close to collapse that a 2% increase in loading would cause failure should be closed immediately. Structural engineering calculations are simply not that precise.
