The top end of motorsports, so yes Formula 1 basically but you can include Formula 2/3/E, the main job of the teams is to build a hyper efficient car.
The car companies who either own or supply their engines are continuously developing more efficient engines which are reliable, fast and light.
The developments of these engines trickle down into the hundreds of millions of cars on the roads today.
Human beings have always strived to invent, progress, explore, part of the process OP you are able to have an online debate live, with others across the nations (I am taking about internet development now not cars just to clarify). Making cars which win, go fast, and being able to drive them, it's incredibly difficult to drive an F1 car, is one of the activities that brings excitement, competition and a display of vehicle engineering at it's finest to the masses.
The servers that are pinging your posts are emitting huge amounts of heat right now, whatever you do, internet, lighting, heating, refrigeration, travel, food especially if you eat red meat, are all energy consuming.
Nobody wants their or their children's living standards to go down, the developing world has an increasing middle-class, raising living standards for many to what has already been reached in developed nations. Energy efficiency in all parts of our lives is going to a major contribution to slowing and adapting to climate change.
Industries, competitions, events that bring in money to companies whom are developing technology is essential and F1 is the showcase of this within the automobile industry, because people are not going to give up private transport without a fight.
We as a species keep moving forward, from the dawning of the human race, it's not going to stop now, even if we do wipe ourselves out in the process.
