Here in Florida we get fined over a thousand dollars for popping a stupid wheelie. If the tire comes off the ground you can hand over about $1300 if a cop wants to push it. They can also take the bike. I had a fellow firefighter pop a wheelie and a cop lit him up. He ran. I don't blame him. If the fine was a couple hundred bucks, it would be lesson learned. Pull over, take your lumps and move on. Nobody can afford that kind of fine. It is out of hand.
While I suspect the OP's example is for really reckless riding, there is no way those guys are going to be able to pay that. They should be punished, no doubt, but the punishment should fit the crime. This is too much.
