I hate seeing Drivers jumping up and down in the sulky, just hate it. Don't they realise what it is doing to the momentum of the horse? It really is a pet hate of mine. I think anyone who drives like this should carry a driver in the sulky and see how it puts them off stride. I know this from countless years of pretending to be a horse at home as a kid and pulling my friends around in Dad's sulkies. Watch a race at globe and you will see a couple of drivers in every race do this.
as far as whip rules I love seeing the horses only being tapped up and not flogged. Much more appealing to the eye.
