Where there's multiple crashes in the same place it often is the road design that's at fault, not the drivers of the cars.

One vaguely relevant example is that roundabouts are safer than 4-way crossings for cars, though I think the evidence is a bit more mixed for cyclists.

Agree. My point was changing driver/cyclist behaviour is not victim blaming, but a valid approach to solving the problem.

Road Design, car design, culture, etc are all valid factors as well.

Well, knowing that roundabouts are safer, if the manufacturer of 4 way stop-lights suggested that cars should be painted brighter colors to prevent crashes, I'd consider that in about as poor taste, and as likely to have a positive impact, as volvo trying to repaint bicycles as a PR pitch.
