The sooner they forget the electric race the better. Let them go back to the drawing board. From what little I know (and it IS little to be fair), there appears to be quite a few supporting the Hydrogen engines, as the way to go in future. Few would dispute that eventually there will HAVE to be alternative modes of transportation. Whether we will want to see them raced is another matter. I reckon that "we", that is those that support the present form of racing, will disperse into other hobbies once the petrol powered racing ceases. There ARE plenty of other things to do in this world.
Right now I'm looking forward to the Manx, which in my opinion is the best motor cycle event in the world. Long may it continue.
