Sometimes people do grow up. Yes, the internet is littered with videos of people doing stupid things, and we have plenty of TV shows of the same. If you've ever watched Dumbest Stuff On Wheels, you wonder what people are thinking.
Parrots really shouldn't be on motorcycles either. Even at slow speeds there are so many things that can go wrong and they would have no protection in a crash. Bikes slide on gravel, oil, coolant, are subject to bird strikes (wild ones), and anything people throw out of cars. A flat tire or mechanical malfunction can be much more dangerous as well on a bike. Even an insect hitting you at high speeds can hurt depending on what kind it is. A large butterfly can obstruct your entire visor. So there are reasons I have never taken an animal for a ride. I have seen people riding with their dogs and even cats, but I choose not to.
But, the simple fact of the matter is, people DO need to think before subjecting an animal or child to something so dangerous. I am an adult human who can make the choice to ride a motorcycle after weighing the possibilities of what may happen to me. My animals can't knowingly make that choice for themselves. They also do not have helmets, leather coats and pants and gloves and boots to lessen the severity of crash injuries.
