It already is … it’s basically F1 deepest pockets and hidden cheating (I say “hidden” but race organisers/marshals don’t seem to care if someone has assistance at 30mph+)
I don’t even think it’s that hidden (well, at stuff below EWS level races).
I’ve been to races where chipped ebikes arn’t allowed, yet people I used to be on a par with (and now on ebikes) are putting huge time into me on flatter stages, yet still similar on steeper stuff. When the average speed is over the motor anyway, you know there is something fishy happening.
The problem is the software is now really good at hiding if a bike is chipped, so a ‘spot check’ will basically prove nothing.
