Any more than that and you'll be asking me for the answer. Take a guess gugi. If you get it wrong you can always guess again.
Well I don't like to guess when I can just compute the correct answer, but that would necessitate unambiguously defined problem

So presuming each car passes through the exit once a minute, and not that 'a car' passes through the exit once a minute, the first car would've passed 30 times during the time of operation and the other 9 cars would've passed 29 times each. Which means the maximum number of people who could've had a full ride is 2*(30+9*29)=582.
