As a commentator on league racing the up to date HUD on broadcasts would be brilliant.
However those saying they want the graphics when out on track, that is, IMO, silly. The screen clutter would be crazy and take up huge amounts of screen area that would normally be used to see who is alongside etc. I don't even see the point of that being optional tbh as that much would, again, be too much on screen at once.
What we have just now I think works well, maybe a bit of spit and polish as they say to make it look good but the full tv HUD while driving, no thanks.
