Good one!

I'm not a big fan of the EV scene, but I could see how it could help with noise restrictions for some tracks. I know the EV fires are real bad, but will be fixed down the road.

I think one of the bigger things would be the lack of noise. You'd have to make some sound emitter that wouldn't fail so the drivers would know where each other are. If it fails someone would probably get sent to the moon off a bad slider.
One fix for that would be mirrors or spotters and that's a thing that should NEVER happen.

I lost interest in the Thunder Boats when the turbines replaced the Merlin engines. The woosh just didn't move me line the noise and the ground literally shaking. The same thing would have happened to Indy Car if they hadn't outlawed the turbine car. To me a part of racing is the sound of all that power. I even enjoy listening to them thumping around during wheel pack.

I also love listening to the cars Thump and mishit at low RPM's. However, electric cars will be racing sooner than you think. We already have 200mph electric drag cars. In 2035, GM's fleet will be all electric. It only makes sense that they will want to race what they are manufacturing. #IWorkForGM
