Tougher penalties hope to put the brakes on boy racers and fleeing drivers.

The Government's establishing a presumptive sentence of vehicle destruction for street racers, those who flee police, and intimidating convoys. 

Police will also get greater powers to manage illegal vehicle gatherings by closing roads or public areas.

He says these aren't just boy racers, they are deliberately antagonising Police, throwing bottles and ramming cars.
