That is an interesting article. I look forward to seeing what these come up with (from the link):
"Related ongoing projects include a study sponsored by The Royal Society for the Prevention of Accidents (RoSPA) looking at the judgments of older drivers at road junctions, as well as a study looking at why motorcycles have a higher risk of being involved in accidents classified as ‘looked but failed to see’."
I was always taught that if there is a car, wait
as I got older I was taught if I couldn't tell what the car was, it was probably safe to cross.
do they really need to investigate why motorbikes aren't seen?
half of the motorbike community are sensible, ride properly and people look round for a car and go, not spotting the bike, especially lane changing and filtering (a friend got bumped by a van filtering in standing traffic the other day)
the other half, the ones that do 80+ down the peak district lanes come much faster than people think they are (as you only expect people to do the speed limit) or are hidden by a corner that's a fair way from the junction, so you pull out to find a bike comes racing round it at top speed
it's not rocket science.
