When I wrote about the difficult situation MotoGP finds itself in with respect to the new front tire Michelin is developing in an attempt to address the increasing problems with tire temperature and pressure, the immediate response, especially on Twitter, was "MotoGP should just ban ride-height devices and aerodynamics". While this is a charming notion, it is also utterly impractical. To paraphrase a quote from a movie about ill-thought out decisions, those commenters were so preoccupied with what MotoGP should, they didn't stop to think whether they could.
If you talk to independent team bosses, they have no love for either aerodynamics or ride-height devices. Similarly, senior officials within Dorna and IRTA have expressed a dislike for both technologies. If they could, they would get ride of ride-height devices tomorrow, and aerodynamics shortly after. Even a severe restriction on aerodynamics would be welcomed.
What Dorna would like to do, and what they can do, are two very different things, however. The formal process for changing the MotoGP technical regulations has been set out in detail, and simply do not allow Dorna to change the rules.
