There's plenty of things that can lead to increased risks when driving. While drinking and using a mobile phone are cracked down on and things like fatigue and being a poor driver are not, it's no excuse to drive drunk or use a mobile because other risk factors aren't clamped down on. It's akin to defending yourself in a murder trial by pointing out that the prosecuting lawyer cheats on his wife and taxes.
