At Bedford they allow 40 cars out on track at once (for the GT circuit), as it is quite a long circuit (4 miles give or take), after the initial rush at the beginning of the day you'll tend to be able to just go out as and when you please as people naturally start to stagger themselves out, maybe have to wait for 1 or 2 minutes in a queue but nothing outrageous.
Thanks, exactly what I wanted to know
