I disagree. Not 'cause I'm a man, though. I think most problems occur when you're combining "wild/fast" drivers on the same roads as "passive/cautious" drivers. It's the difference in driving technique & reaction that often result in some sort of crash. If everyone is driving fast, and in a similar way, movement is fairly uniform, reactions are predictable and so, there's less variation on the road. When you combine the different type of drivers, you end up with varied reactions and stability, less predictability and the end result is more road conflict.
Personally, I'd rather drive with someone going fast, who is aware of their vehicle, the road, and what's happening around them, then someone who's driving slow, but is afraid and uncomfortable behind the wheel and reluctant to react to the environmental conditions and other drivers.
