Marty, I guess from what your saying is you only need to advise if you intend to drive differently. So by default if you are driving the same the other already know what you are doing, so the COT rule allows the opposition to know what you are doing all the time!!! If the stewards see that a driver/trainer has just been giving a horse a run they still have the powers to charge them for not giving their horse every chance retrospectively.

When I see a stewards report and I read COT and driven accordingly it makes me scream. I would rather see that the driver is asked after the race and he explains the reasons why the horse was driven differently it would show who knows how to read a race and form and who doesnt.
