Is the car industry trying to justify price hikes , and seen to be going green . Hydrogen is not green , its production uses excessive amounts of energy . Also we will see if current vehicles especially the power trains will cope with the high torque of electric motors , and the electronic systems will cope with bad conditions and maintenance .
Also will the constructeurs be producing several types of vehicles in the future , as less wealthy nations will not be going to Hybride units for a long time .And unless the whole of the EU has installations for hybride units , its a waste of time , as people travel from one end of Europe to another , and with no maintenance or filling facilities then its a no go , and a waste of time and money .
Sorry to say the constructeurs and talking lot of hot air , along with the politicians.
The real problem is overpopulation and concentration , without dealing with this , its all useless .
