The rospa.org.uk site says 80% of the drivers that hit cyclists are male. The bicycleaustin.info site says in 90% of the cases in which a pedestrian is hit and killed the driver is male, bicycleuniverse.info says the same thing, I'm guessing the same stat is true of cyclists hit. I recall reading a stat somewhere that most drivers who hit peds or cyclists are males in their 20s and 30s. So you are more likely to get hit by a male driver AND if you're hit by a male driver your less likely to survive it. I tried to add the link but can't, but you can google it.
If you google 'cyclist hit' you will find articles about cyclists that got hit and often they tell the sex and age of the driver.
Why are male drivers the ones usually involved in hitting vulnerable road users (bicycles, pedestrians, motorcyles)? Is it mainly because theres more male drivers on the road?
