I believe that Grand Prix racing has remained popular because it is willing to make changes. These changes over seven decades were not popular at the time. Transition from road chains to specially built tracks. Abolition of 250cc and 500cc two-stroke engines for four-strokes in Moto2™ and 3 and MotoGP™. The qualifying split and even last week the announcement of the arrival of sprint races next season. I, like many others of my generation, have not always agreed with these changes, but they are necessary if our sport is to survive in an ever-changing world. Sure, mistakes were made, but standing still or going backwards will never work.
