It is like cricket, you have those that enjoy the Test/5 day game, and those that prefer the "100".. Lewis's League would attract viewers that are not interested in F1, that would not be a bad thing, F1 would change/not chage as a result. There was talk a few years ago if a breakaway league, but this was defeated...
I see no problem with a 2nd alternate, we already have an alternate, E-Prix, which here is so badly marketed I have no idea when it was broadcast, it was, but the broadcaster here makes no effort to alert to it's broadcast..
Sad that this happens..
