The dominant cause of pedestrian deaths is the same as drivers: alcohol. But unlike drivers, pedestrian are allowed to walk around drunk. So we dont even talk about it. We pretend it doesnt happen. It does. It happens all the time. The drunk pedestrian being hit by a car is the norm.
>>2008, nearly 40 per cent of pedestrians killed on Canadian roads were impaired, with two-thirds of them having a blood alcohol concentration more than double the legal limit. In fact, of all the fatally injured pedestrians with alcohol in their systems, fewer than one in five was at or below the legal driving limit of 0.08 blood alcohol concentration (BAC), according to the Canadian Council of Motor Transport Administrators* (CCMTA).

And just try discussing drunk biking and you will be run out of town by a spandex army shouting about thier "right" to use the roads while drunk or high.
Just the other day, a middle aged cyclist decided to hug my bumper as I went downhill at about 35 mph. I rolled down the window and shouted "back off please". He looked surprised, but backed off.
A bicycle's brakes are far less effective than a car's. I don't know how a man got to middle age not knowing this. A lot of cyclists ride like they have an invisible shield protecting them.
