The Labour MP said up to 400 cars are congregating in Dartford and Essex and racing along a route which covers the Blackwall Tunnel and the Limehouse Link.
Mr Fitzpatrick, who has written to Tower Hamlets Police and the council demanding action on the organised events, also said the cars are using the tunnels at Westferry Circus to regroup and film stunts.
He pointed out a YouTube video from October 20 which saw an estimated 265 Japanese fast cars gather in the roads under the Canary Wharf estate.
Mr Fitzpatrick said: “These cars use the tunnels and the route for no other purpose than to showcase the sound and speed of their cars. Videos posted online show dangerous and loud street car racing which belongs in a Hollywood movie and not the streets of east London.
“As well as causing a disturbance to residents the fast cars endanger motorists on the road. We need these tunnels runs off the road which means a dispersal zone and barriers on race nights.”
