AUSTIN -- The owner of the Circuit of the Americas (COTA), home to this weekend's U.S. Grand Prix, believes F1 risks diluting its product as it pushes ahead with a race "around the parking lot" surrounding Miami's Hard Rock Stadium.
The U.S. GP in Austin has become one of the most popular venues on the calendar since joining in 2012 and during that time has been the only race in America. F1 owners Liberty Media promised to add more when it took control of the sport in 2017 and has been in protracted negotiations with a consortium led by Miami Dolphins chief Stephen Ross about a future race there.
