As long as you can see what's happening on the track, why do you need to see it in HD? Doesn't make sense to me, I've never seen the point in HD, all it does is make objects seem so crisp that they look pixellated. If anything I see it as a step back, plus how you receive HD depends on what TV you have, some are better than others, where as normal TV, it doesn't matter really what TV you have, they will all pick out the same picture. Instead of translating it into their own realization of 'HD'.
