The issue is of why deaths happen isn't due to gas, its because F1 is simulatenously "build the fastest car that can hold incredible speeds in corners", and "we are going to put restrictions on when you can use technology to make racing fair"

Look at Moto GP. The crash speeds are much slower, because they happen during cornering, and because bikes don't have that much aero downforce even with all the power ranger wings on them now, the riders have to brake a lot more.

Instead of trying to push hybrid tech, which will never be that good for racing, Id like to see F1 focus more on actual ICE engine refinement, because ICE isn't going anywhere even in the age of evs. Something like no front/rear wings, no pitstops, ICE only, standard ECU for power delivery, no ABS, but you can run AWD with electronic suspension and torque vector as much as you want.
