I agree, I nearly ran over a youth pulling such a stunt earlier on in the year, driving around West Place and trying to undertake my car as I was driving past. Police were informed and the situation was dealt with, but I do see them regularly still doing what they do.
The same youths were caught stealing motorbikes from my house in broad daylight.... Maybe the cash spent on a racetrack could be better spent on more community police.
Even if they had a track to ride their bikes, would they be encouraged to use it? Some people just like the risk. I'm all for getting kids off the streets, but are they willing to be taken off the streets.
