Ah, but I disagree. I'm not one for regulation, but Jeff, it IS an amusement ride. Vehicle or not, it's in an amusement park, and it is a ride.
I will agree that cars are more dangerous than every other type of amusement ride, but these cars are part of this amusement ride, thus making this ride inherently more dangerous than, say, a roller coaster. Human error definately plays more a role in this ride.
As I said.... I'm conservative politically and think less government is better, meaning I don't want to see government regulation of amusement parks.
