At night, the fresh tarmac of Islington's new Waterloo Business Park becomes a race track for cars, motor-cycles and even karts.
Those living in nearby residential Brixton, Wilson and Mortlake Sts are being kept up by a chorus of revving, skidding, racing and burnouts.
And when developers of the business park go to work on a Monday morning, they often find empty bottles and rubbish strewn across footpaths, gardens and the street, as well as the black tyre marks all over the roads.
Residents and businesses are fed up, Waterloo Business Park project manager Ashley McLachlan said.
"Sadly, there has been a small number of people using the roads and parks in a destructive manner, which impacts on the businesses based here and our neighbours. We want people from our community to feel welcome and safe," he said.
