There's too much talk of individual behavior when it comes to vehicle and pedestrian safety issues. Of course individual behavior matters, but it tends to lead to mostly pointless arguments about whether cyclists, pedestrians, or drivers are "the worst." We know how to design streets that emphasize safety over traffic throughput, and that street design is probably a lot more important than yelling at bad drivers or even traffic enforcement. Design a highway and drivers will treat it like a highway. Institute various traffic calming measures and they'll slow down. Have separated bike lanes and cyclists are safer. Time lights for pedestrian crossings appropriately and pedestrians will be safer. There are lots of things.
And, yes, as it says in the link, a big problem is that SUVs kill people because of the way they are designed.
