[1] In 1965 the U.S. Grand Prix returned for the second time at Daytona, but privateers were unable to pay for the trip to the United States and few Americans went to see the race due to the lack of interest in the majority European-styled championship.

[1][4] As a result of the lack of interest from the American public, top teams and riders, the United States Grand Prix was removed from the 1966 season.

[4] That year's event was marred with problems as many especially European riders complained about the bumpyness of an old part of the track and the dangerously close barriers and concrete blocs that surrounded the circuit.

Against the rules some sold tickets in front of the riders' quarter's, the prize money was unusual, the supply roads were insufficient and kept getting altered and the timekeeping produced useful times only after 18 hours.

[5] On top of that, the American organizers wanted to include a sidecar race in their program but refused to pay the extra travel expenses.

[6] During the race, an ambulance drove on the track in dangerous manner to assist the crashed out Wayne Gardner who had broken his leg after a heavy shunt exiting Turn 5, with no yellow flags being shown to the riders.

A bizarre incident occurred on the cooldown lap of the 1989 Grand Prix, when Bubba Shobert hit the back of Kevin Magee's motorcycle at high speed after he failed to see the Australian.

[14][4] The 2008 United States Grand Prix saw a thrilling battle between Valentino Rossi and Casey Stoner, the race being won by the Italian in the end.
