Are you serious? When was the last time you watched a Formula 1 race? It was boring because there weren't any restrictions, and so the best teams were so far ahead the races just became a procession. That and the high downforce setups being badly affected by running behind other cars, coupled with tires that didn't wear out much, made overtaking almost non existent. In the last 6 seasons, we've had 4 championships de…
Formula 1 was also technological race, that is now gone. Why should top teams invest into innovation anymore? F1 today is just street race with oddly shaped cars.
Because the FIA limited the placement and size of aerodynamic fins (i.e. spoilers and front lips), the engineers started using other aerodynamic innovations to increase downforce. One of the most interesting things to come out of F1 cars, from an aerospace engineering perspective, is the use of eddies and other circular air motions underneath the vehicle to drop the pressure (and create a corresponding downforce).
Just because the rules stop innovation on something like engine tech doesn't mean innovation stops; it just means it moves to optimizing other pieces of tech.
