Next Problem for me: I need a car that allows me to tow my trailer...
There is not one that will tow 3.5T - yet.
When we had a u3a visit to Intelligent Energy (A Loughborough University spinout), the people there said that they thought the market would polarise:
Shopping trollies etc and local delivery vans = Battery
Large Goods Vehicles, big SUV's and luxury cars = Hydrogen Fuel Cell
But then they would say that as they make fuel cells. They were prohibited from telling us which manufacturers they were already working with.
