So we have range, charging and cost.
Range,
Driving over 200 miles without a break is IMO unsafe but there are those who clearly do it. Cars with a range of 450 miles on a single charge are few and far between. If any do arrive on the scheme, (very unlikely) within the next three years the AP will be sky high. So paying through the nose rather than stopping for an hour to get a bit to eat and recharge seems like a very acceptable compromise on the very few times you need to do it.
Charging
there are those like Laura above who are in difficult locations and will struggle to go full BEV until there are many more more chargers available. However it is doable for her, and anyone else to charge away from home. A quick search on ZapMap https://www.zap-map.com/live/ will more than likely reveal a number of charging points in your area, also if you work there are grants coming in April next year to encourage employers to install chargers.
What i would like to see is dedicated disabled parking with a charger outside disabled drivers houses, ensuring they can charge and get a dedicated parking space.
Cost
EVs are more expensive than ICE cars at this point in time and its likey to stay that way for three years or so but by 2025 the cost of EVs are predicted to go down by 25%. If this is the case the Motability scheme will be a whole lot cheaper. Thats the future though, right now it could be much cheaper over the three year period depending on your mileage and whether or not you can charge at home. There have been numerous posts as to how much cheaper it is to run an EV compared to an ICE car.
