But as they say in the article, the helmet data for fatalities is meaningless without data for the number of cyclists wearing helmets.
I'm probably out-of-date as I haven't driven in the states for some time, but when I did (much of southern US), I found drivers particularly tolerant and much more "laid-back" than in the UK. You could be waiting at the from of a line of cars at lights, fail to notice the lights change, be too late as they turn back to red and the queue would happily wait behind you no hooting, just quietly waiting. Whereas UK many drivers seem to be in a mad rush to get everywhere and rather impatient.
The rear-end risks are interesting. (Noting that most of my riding is done on single track rural roads) I tend to pay less attention to cars approaching from behind than those from in front (except when manoeuvring). I assume this is because I think of them as having more time to see me and our relative speeds as lower than for a car approaching from ahead. But thinking about it I can see a possible reason for the increased injury (or risk of being killed) from a rear-end; when colliding head-on I'd assume you tend to end-up on top of the vehicle bonnet whereas with a rear-end you are more likely to end-up under the vehicle. Both sound pretty nasty.
There is nothing I can see identifying "car-dooring". Particularly in my mind today as I nearly had a car hit me from ahead as I was NOT prepared to move into the "car-door" zone and they were not prepared to wait in the section of road where there no parked cars.
