The fire safety and comfort of the rider and pit crew would and could be very much improved if they(hoping they do) also got rid of those dark ages fuel filler guns which only supply fuel in a manic 'full on" or nothing style, surely there's a fuel filler / gun out there that delivers fuel in a progressive manner so that the rider and bike aren't covered in "full on" delivery fuel when trying to fill the last little bit in the tank which is crucial for some bikes to get 2 laps out of a tank.
