When one vehicle in a motor race drives behind another, the trailing one benefits from a reduction in drag.
They can lurk in this position and use the power reserve and fuel saving it allows to perform a sudden overtaking manoeuvre when the timing suits them.
This represents an unfair asymmetry in such sports -with very powerful vehicles able to slipstream the less powerful but not vice versa (since the fast cars or bikes can more easily pull away).
Today’s invention is therefore a sensor which detects when one bike for example is travelling directly behind and close to another.
In this instance, the following machine’s rev limiter kicks in, in order to make the race more about driving skill than vehicle design/tuning.
