Agree with computedshorty. Drivers should check their blind spots. But they also have to look at the road ahead for dangers. that turning is an immediate left after the goose green roundabout, about 10 ft. If one demands that the driver check their blind spot for cyclists, negotiate the left turn off the roundabout, check for pedestrians at the crossing, check for pedestrians crossing the road they are about to turn into, check their blind spot again...then that person is not a safe cyclist in my view. one can't tailgate a car, sit on their inside rear wheel then try and undertake next to a left turn. Us cyclists need to take some responsibility for due care and attention as well.
