I would tell this to my friends after I'd have a few beers and grab the wheel, but they're asshats and can't drive properly anyway so they never understood. Then one day they all got in the car with me after I'd had a couple rum and cokes without them knowing, we got there, I said OH BTW I'M DRUNK and everyone freaked out because I was driving completely normally and no one noticed for the 25 minutes we were in the car.
If I feel that my ability will at all, in any way, be hampered - I won't drive. Simple as that. I'll walk an hour in a fucking blizzard (like two nights ago) rather than drive and take a risk if I know I'm somewhat affected.
However, unlike the vast majority of asshats, I know my limit. I've worked at two dealerships during summers between school where I was in/out of dozens of cars daily, driving in the worst conditions, hungover, tired as shit, in a big city full of immigrants where the driving is cutthroat anyway. Usually on my cell with a manager or a customer.
There's only been one or two times where I drove where I knew I shouldn't have been, and it was in a secluded residential area - but even then, I know for a fact I was safer than the vast majority of retards on the road when sober. Most people simply can't drive fucking cars. They don't pay attention to the road, they don't try to think about things ahead of time, they don't give themselves a buffer zone... the list goes on.
For this reason and this reason alone I've always found DUI charges to be ludicrous. I'm afraid to get in the car with some of my friends when they're sober because they don't check their fucking blindspots, they don't know how to control a car in bad weather (or good weather for that matter) and simply are bad drivers. If anything ever happened, they'd be dead.
Meanwhile I could out-drive them with a few beers and yet my life runs the risk of being ruined.
Go figure.
