I like the American commentators on the Speed channel!
While I, too, hate the commercial interruptions, F1 is still the best racing going on American TV at the moment. For a couple of years, one of our major networks carried four F1 races on their schedule, but their announcers were so appallingly BAD that I had to turn down the sound.
What F1 - and all other open wheel racing - really needs is to ban all aerodynamic devices. I am old enough to remember the glory days when the drivers sat upright and sawed away at huge steering wheels as they fought their beasts around the bends while wearing only a light coverall, canvas or leather helmet and goggles. The American open wheel drivers even wore t-shirts mostly. The cars may have been going only half as fast, but it seemed as if they were much faster than the cars of today.
And don't get me started about stock cars! Bring back the Hudson Hornets and other cars of the 50s, cars I could actually tell apart and which bore at least a reasonable resemblance to cars one could actually buy, and maybe I would tune in again. I reckon I'm just too old...
