As the audience for autosports increasingly skews older and smaller (as the elders die off), those who promote the sport have the intractable problem of automobiles are much less relevant to the younger audience who could sustain the future. Here's a link to an article that explains how in the USA the ownership and everyday use of automobiles is markedly down somewhat because the Millennial generation find them a bit of a waste of time and money. Rolling from place to place to do business seems a bit quaint and wasteful in an age where most everything can be done online. Hence the rise of on-demand transportation (enabled via online systems) and their acceptance of a future with self-driving vehicles. In the self-driving vehicle, you can keep working, shopping, socializing, etc. while on the way to that necessarily in-person event.
