Ain’t gonna happen for a long long time.
The fact is, electric vans are pants for payload and range.
We need diesel!
Milk floats did ok with all them glass bottles on ? And technology has reduced battery size. Also anyone with a manual reel could attach a dynamo and charge the battery up as they reel in 
They also had a top speed of about 20mph 😜
In all seriousness, we’re going to need to burn a heck of a lot of fossil fuel to provide the power needed to charge millions of electric vehicles.
The whole thing is a joke really, especially when you consider how clean modern engines are.
It’s mostly a money spinner, more tax, more money for the government.
It’s going to be very difficult for the national grid to supply enough electricity for all these electric cars.
Check out fully charged. They are really informative with anything green but vehicles in particular. Modern cars might be cleaner to the eye compared to old vehicles but they still convert fossil fuels that were once trapped in the earth into gasses.
The entire thing is not a money spinner. If it was about making money it would have all happened by now. What slows it all down in my view is people being miss informed. It’s going so slow because of money. The planet runs of fossil fuels. Country’s and huge corporations make money and fight over it. Corruption to ensure people who make big money off fossil fuels continue to earn a lot of money. Think eventually we will see some sort of tax like fuel duty to cover the money lost to the government.
https://www.youtube.com/user/fullychargedshow/featuredTesla have there batterys right across the floor yes. But all the other manufacturers don’t Necessarily do that. It’s a bit like having a tank fitted into your van but avoiding the fuel tank. Putting mountings around where the fuel tank is or dropping the fuel tank. Same sort of thing can be done with an electric van.
I’m planning on running my current van for the next 5 years and see how it goes. After that I will be going electric. It will be more clear cut and make more sense by 5 years time.
Someone told me in the trade that the BIK will be improving for electric cars so we will see a load extra on the road the next could of years. A bit how weve seen all the plug in hybrids. Like the BMW 330e that the managers have been getting as company cars.
They are a bit behind in making electric vans. The only one worth having is the Nissan e-nv200. But it’s a little small and girly looking for my liking. If it took 900kg I would consider swapping my van if it broke though.
