Ready? One,Two,Go!

City. Two-wheels.A starting line...
It is the dance of the motor-bikes. It goes with the music of the engines. There is a red projector that regulates the start. So the bikers must slide in between the vehicles to get to the zebra departing line. They like to regulate their engine music before.
The spotlight turns GREEN! Off they go full speed on and the dance between all the vehicles continues. The idea is to reach the destination as fast as possible...sometimes, at your own risk.
It is not a pleasant task to be on two legs. You become a silent dancer, a bit like a bullfighter facing the Minotaur!
