Jonathan Mears, 39, said: “The cycle lane is wide enough to stage the Tour de France. But there isn’t enough room left for an average sized car.

The AA has said it could push conscientious drivers into oncoming traffic.
The lane was ‘wide enough to stage the Tour de France’, said resident Jonathan Mears, 39. The markings were for guidance only, said Poole Council.
Spokesman Paul Watters said: “Drivers may be worried about breaking the law by crossing the line – even though they are allowed to – and end up straying into the oncoming lane.
The council said: “The markings are advisory and are there primarily to remind motorists to give space to cyclists.”
