Much as I approve of speed cameras to help prevent general speeding, they aren't going to stop the antisocial behaviours described by ACH. And even if they did cause a minor success in Queensferry, the boy racers will simply move elsewhere.
If I were in the shoes of a politician wanting to do something meaningful, I'd start by banning "pop-and-crackle" kits nationwide. With heavy fines, along with citizen reporting through video footage and a police web-portal.
A single car with a pop-and-crackle kit can literally wake up tens of thousands of residents, when driven at night through a city.
And let's not forget the underlying causes of antisocial behaviour, namely:
- lack of amenities accessible on foot (particularly relevant to teenagers not yet able to drive, and so embedding car culture from an early age)
- lack of community caused by car-dominated planning and lack of investment*
- car culture, "drive everywhere" mentality, particularly in satelite towns
*no money to invest because they are spending absurd amounts of it accomodating cars in towns and cities
