Accidents do happen and you don't have to be drunk to be involved in one.
Yes, that's absolutely true but, if you're driving drunk, the chances of
having an accident are hugely increased and, because the driver is protected in a car, it's usually pedestrians, children, cyclists and non car drivers who die when the car slews off the road. Yes, cars without drunken drivers slew off the road too but it's a lot less likely.
Yes, attitudes to things do change, thank God, and it's changed re drinking and driving/drugs etc. The press abounds with instances of drunk drivers killing innocent people. Lives are ruined, mothers lose their children, husbands lose their wives, families are devastated and all because someone drives drunk. My advice to any drink driver is to imagine if it's your mother, child, wife or whatever who is at the side of the road bleeding to death, then a lifetime without them. That is not being 'holier than thou', you know. There are many people out there, probably some on this forum, who have driven over the limit but simply who have not been caught like you were.
The point is, needless deaths of other people by drivers who can't control their vehicles properly needs to be stopped. Surely you would agree with that? Then after doing the time for the crime, as it were, start afresh.
