few possible scenarios to help stop drafting at events....
1.
next race after being caught you have to wear a bright orange tri shoot with a big black D on .....you also have to sign in at the big orange tent with the banner "drafters sign in here"
2.
you have to wear a total black tri suit at your next race, sleeves too - .... you are forced to slow down to stop yourself over heating...
3.
possible production of gas cannisters, like the CO2 ones, but reversed so they point out and have a push button system so you can release a small jet of pepper spray, anthrax or other such lethal concuctions! ..... a control panel would be wireless (very cool) and inserted into you aerobars, or better still adapted to work with salt sticks! (salt stick take note)
4.
races employ more bike and camera crew..... but the cameras are not real they are in fact paint ball guns, anyone spotted drafting gets shot at, but only at your legs.
5.
(...my favourite).... timing chips have gps and so on in the, but also are positioned so that they run along the nerves (acupressure stuff), perhaps even a hand tag, when the control sees that 2 items are, and have been too close a signal is emitted and a short sharp shock is released, or the device pushes on a nerve that shuts your legs down.

Take away your aero bars. You get caught drafting and next race you are not allowed to race with aero bars, simple as that. But you have to serve your penalty in order to race again.
Any other solutions…
