Typically American but growing quite big in Australia and typically male dominated (ladies, let’s get involved), the monster truck rallies are big in every way. The trucks are modified four- wheel- drive vehicles, with the truck body sitting way up on top of tyres six-feet high and almost four-feet wide. Such vehicles would never be allowed on the road even though they are in great working order - they have to be towed to the stadiums where they put on their shows. They compete by driving off an elevated ramp and seeing how many cars they can crush beneath them before reach to a stop. Between 15 and 25 cars are crushed during the average rally.
