RLJ (Red Light Jumping). (The definitive bikeradar thread)

Momentum I dooubt many London lights use induction anyway since there are always cars at all the lights on a junction. They probably use timers or something. Plus I don't think emergency services have any kind of special light changing gizmos since they always just go through red lights with siren and flashers on full bollocks.

yeah most london traffic lights are timed to work in blocks to get the flow moving smoothly (in theory) esp. in busy streets like Euston Road. 'Cept traffic always seems to move faster when the lights are broke.
