Highway here is a pun given the roads are considered to be not only those on the ground but corridors in the sky for broomstick and other flying methods. Both types of highway are policed. And there is nothing more detested by the fairy squad than having to clear away dead bodies because witches were offended and cursed someone, or because there have been accidents.
Here accidents tend to be caused by speed. The realm condemns this not directly for the speed but because it meant someone couldn’t handle that speed. The attitude is if you can’t handle it, you don’t do it and this applies to other areas of Kingdom life as well.
Hanastrew is more involved with the criminal catching side of the fairy squad’s work but she does oversee the traffic side from time to time. In certain areas where congestion is a pain on the road and in the sky, she persuaded the Queen and her Council to bring in speed restrictions. Hanastrew would be the traffic warden’s traffic warden!
Hanastrew likes the CCTV cameras we have on Earth and is working on a way of bringing into a magical equivalent. Copying the basic design and build is no problem but protecting them from being magically obliterated is full of difficulties given all magical beings can and do use imaginative uses of magic to get rid of what they don’t like. Until Hanastrew can bring in something that would be 100% magic proof, there probably isn’t a place in the Kingdom for speed cameras.
Hanastrew also likes the Stinger which is thrown across roads, usually motorways, to bring speeding cars (usually well over the limit) to a halt by puncturing and slowly deflating the tyres. She wants an equivalent that will pull bristles out of broomsticks and make it impossible for the broomstick owner to replace them. Hanastrew works on this spell in her spare time. When asked she says it is under development but this has been the case for months. This scenario is unlikely to change much. Her attempts to instill some kind of discipline are welcomed by the government.
