TBH I thought the suggested layouts for Miami so far have been poor.
I'm also not such a huge fan of street circuits.
Monaco, obviously, is a spectacle. But the others are all a compromise making fast cars drive through pretty but unsuitable places. I guess it shakes things up, but for me a GP race needs (mostly) a GP circuit to show the sport doing what it does best. I get why Liberty would go for it - America, audience ratings, money - and why venues like 'em - cheaper up-front, tourism factor, etc. But that's taking the eye off the oily-rag ball. If it's glitz and cheap, lightly-interested audiences they want, they should send in Judith Chalmers (if she's still necking sangria in this world).
Give me speed, noise, insane driving skills, bewildering engineering and heart-stopping racing. Stuff the marinas, grid kids and celeb-studded carpetting.
When Liberty finally decides it can make more money from re-runs of M*A*S*H, and jettisons F1 like a turd in a trebuchet, there'll still be an audience of grey-bearded loons marvelling over the late braking and howl of engines.
I may have had a beer or two.
