**WHEN** they become common. combustion engines aren't going to disappear anytime soon, especially in motorsports,but EV's are the future. We can either hop on board or get left behind. Lots of indoor kart tracks already have electric karts, not sure how weight compares to their combustion counterparts. But once that tech becomes affordable/lightweight, then we'll start seeing more and more of them....puts a smile on my face thinking about an electric rwyb kart with a silly amount of torque skating it's way around a track^^ you can regulate how aggressive the take-off is, and have anti-spin too....electrics will DOMINATE if they become common and the energy density of batteries allows for competitive weights.
I last raced the slot car wing car nats in 2004 in tulsa ok....even back then, a racer was talking to a friend not watching their car while holding their controller wide open...^^ Slot cars are ridiculous these days....it's not "driving" anymore. Give me some spongees on t-jets....now that took skill.
