I agree that motorist need to be made aware of motorcyclists on the road and about pulling out at junctions etc.
However, I think motorist are not the only reason there are motorcycle accidents. Bikers are sometimes to be blamed as well.
I live near a road that is popular for bikers because of its long straight stretch.
I can be driving it and often bikers pull out from a junction on me, trying to have a quick get away.
There have been quite a few times where I have thought that the biker has had a lucky escape but the motorist was not to blame. The biker either under estimated someone's time and distance and took a chance.
I m NOT anti bikes at all. I love them but I do think the radio and poster campaigns seem to be putting the blame on the motorist tbh.
