"...come up with a real F1 track"
??
Watkins Glen hosted the USGP from 1961-1980 and is a much more interesting track than anything they've used since.
And I thoroughly agree that street circuits are wretched. Most drivers do not like them, and they are horrible for spectators; you either sit at one place and watch one little section of the track or you wander through crowds and back alleys to find different viewpoints and miss most of the race. Better to stay home and watch on TV. As for racing, the slightest mistake and you're into a concrete barricade; if you spin and hit nothing you will be hit by other cars since there's nowhere to go to avoid a collision. (Not to mention few cities are willing to tolerate the cost and aggravation of hosting them very long. Our city bailed after hosting a downtown IMSA race for four years.)
