that noone here has ever driven whilst tired, or perhaps had an argument with their kids / OH whilst driving, never glanced at a map?
Driving whilst tired: I tend to stop for a nap periodically if I feel my judgement is impaired
Arguing: Never in a car, I save it til we've stopped
Glancing at maps: yes, but then I realised how stupid I was being and I don't do it any more. Bought satnav to avoid having to pull over all the time
So inconvenience all road users for a tiny minority who are stupid?
Danm right. You do not have a right to do whatever you like whilst driving. Driving is a licensed privilege, and a dangerous activity which requires everyone to play by the rules and do it properly. So why the hell don't the law makers grow a pair and treat it like that.
Imagine the people working in a chemical plant or nuclear powerstation f*cking about and being so generally careless as motorists? There'd be a scandal.
