I was going to say I'd seen a couple of EVs running at Shelsley last summer.
I was interested to note they were constantly plugged into the mains in the paddock between runs and the Telsa (Model 3 ?) had a very loud internal cooling fan running that I've not noticed from other charging EVs in car parks, so even a 30-second run up SW must have got it hot'n'bothered.
I suspect speed events might be the first of the amateur level competitions to allow hybrids and/or EVs due to lower speeds and lack of car-to-car incidents.
Also, venues without return roads will allow for some re-gen braking on the downhill runs back to the paddock
