I've just written an email to a sympathetic local councillor asking them to install average speed cameras on two busy roads I live near where speeding is happening by often the same drivers every single day.
One of the roads I'm near is a 20 m.p.h. zone and is consistently ignored. Another is a faster road but one on which especially young drivers are showing off and being anti-social on, I believe possibly as a way to test the waters of what they can get away with, and in the typical fashion of young rebelliousness. While I appreciate speeding isn't the worst thing in the world it's a noise nuisance and in my opinion affects local businesses and the desirability of an area.
If I was opening a business I'd rather be somewhere where people are somewhat polite and respectful. Hopefully the issue will manage to be resolved.
