I agree here....

Case 1

Ever seen a pacer you fancied give up the lead and be driven to three back the fence, when it had the speed and ability to lead all the way.

Case 2

Ever seen a pacer be pulled out three wide and sit there the whole way. It had the ability to rush up to the leaders and even get a one - one sit for the rest of the final lap, but instead just sits three wide!

Driver has two options - drop back in last place and wait for the final straight, or push forward.
When they do neither, you know somethings dodgy when there's a clear run.
