If they currently pit every 35-39 minutes or so, it wouldn't be completely impractical to pit every 30 minutes or so: have pit crews do a quick swap of the electric batteries at the same time as a the tire change.

- hcho 16y agoHow is it more impractical than changing the tires?
- dtegart 16y agoWell batteries are much much heavier and would likely be in the centre of the car for weight distribution, and you need to make the electrical connection. Changing a tyre during a race just takes a speed gun and one nut.
- Oxryly 16y agoYou just need to develop some sort of "liquid battery" and pump it in some sort of receptacle, or tank, in the car.
