F1 does a great job of telling a story. the racing itself isn't too exciting, but as a casual spectator it's much more accessible to somebody like me who doesn't really follow it at all but pays attention once in a while. the rivalries are well publicized and the races are obvious. I have no clue what's going on in a rally race, but if i'm over at somebody's place and they've got F1 on the tv, i can probably find something about it to enjoy.
