Of course I can drive after a few social pints
Like most people, I know that drinking and driving is dumb. But also, like most people, I do not have much idea of how alcohol affects my driving.
I know how it affects my ability to say and do things that I may later regret. But none of them have ever happened behind the wheel.
I have been breathalysed four times and always been zero. On three of those occasions I had not had a drink. On the fourth I had been at a birthday party and had my last of three glasses of wine by 10 and went home at 1.30.
