"More than one in five cyclists go unseen by motorists on the road,
according to an experiment using eye tracking technology conducted for
the insurance company Direct Line, confirming the extent of the ‘SMIDSY’
– ‘Sorry mate, I didn’t see you. Younger drivers missed spotting nearly
one in three riders, and female motorists one in four. By contrast, just
4 per cent of what Direct Line terms "jaywalking" pedestrians were not
seen, and 15 per cent of motorcyclists."
