Across the pond, they're field testing an electronic safety shield, designed to spot and indicate the presence of cyclists and pedestrians around trucks, and alert the driver. This can be a real boost to safety in the traffic mix.
However we don't have to wait. There's also a very good instructional initiative and video called exchanging places, for both drivers and cyclists, about the hidden dangers of bicycles in the blind spot (pun intended)
Everyone who rides on roads should watch, and pass it along to friends, both cyclists and drivers.
