petrol/electric hybrid vans - why not?


It is a no brainer for any logistics company to switch to petrol/
electric van:

_it will make big savings in fuel cost.

_exempt from the congestion charge

_electric motors are the reliable

I don't know why those companies(like Ford, Vauxhall, Citroen and
Mercedes Benz) are not using them and
car companies are not building them?
