Boy racers - abbey Street & Jamaica road

What's going on with all the souped up cars around Abbey Street and old Jamaica road on Sunday evening?
Stupidly noisy, wheel spinng and speeding.
Last week i was cycling down abbey Street when two speeding cars came at me on the wrong side of the road as they were over taking a bus.
Is this a regular occurrence?

It happens once a year. It's some idiots get together, most of them coming from Essex. The Met warned the organisers about it. There was a piece in the Standard in the last couple of weeks.

I find the link you referred to:

The police didn't seem to be very effective.

Blackfriars Road, Southwark Street and Stamford Street as well. Very painful and tedious.
