I watched it. Seeing the reduced range of the 9 year old leaf shows that electric cars aren't the future. As no one will want to keep a car which has an unpredictable range. As such I can see a cars life span being reduced from the current average of 13 years down to something like 7-8 years. Which will mean the production cost of the use of carbon will increase. I do not believe electric cars are the future. Synthetic fuel is the future.
Plus free tax and cheap running costs will disappear once the majority have them. Road tax will be put on them, plus I can see the electric chargers will be monitored. Ie. Instead of paying one electric bill currently you will have two. Once for conventional electric use for home and a separate one for the car charger. The car charger will be a smart charger so they can know. At which point the government will engineer it so you Pay at least £60 for a full charge.
