The Grants will surely go but that should be outweighed by lower costs for batteries. Note that diesels were (still are ?) more expensive to buy than their petrol equivalent but still became common place on their own merits.
Wall chargers are an upfront one. The price should go down but it gives you access to domestic electricity prices, so people will bite the bullet to get the saving. Same applies to solar PVs.
Free public charging won't survive rising popularity but until it is more viable to own an EV without access to a home charging point, it will have limited impact.
The real threat for me is that a transportation tax (grid upgrade cost would be a perfect excuse) is applied to home charging Kwh....
It would leave EVs to convince buyers on their technical merits alone. It will happen but will surely be much slower.
