ICE is dead, and none of the developments make it to road cars anyway. Meanwhile, battery/EV tech needs all the development it can get and F1’s have been frozen for years.
Make F1 road relevant again, not just aerospace on bubble gum tires. Let teams compete on the tech that actually matters to the motoring world.
A battery tech arms race would be so great. Have three or more battery tech poviders compete and teams are free to pick.
