But the worst part he said whilst cycling to epping forest was that it actually made cyclist more jumpy when they saw the green light approaching and usually made them serve more closer to the pavement and one time almost caused a cyclist to crash.

As in, when he approached a cyclist from behind (oo'er) travelling in the same direction, the sudden appearance of a blurry green image under their tyres had them startled and nearly made them crash?

Not saying this didn't happen, but I'd like to think that most cyclists would not immediately lose control from seeing an inexplicable image projected onto the road.
