Ill give my own drunk driving experience, which I'm terribly ashamed of. I struggle with drinking a lot, now if I know I'm even going to have one drink I don't take my car, yeah public transit in my city isn't great but its better then a DUI or killing someone while driving drunk. Its all about a mindset, as of last year my mind really changed when it comes to drinking and driving.
Example 1: I was 19 leaving a friends house to go to another friends house, I was driving and had 5 beers at my first friends house on the way to my other friends house I got pulled over, he smelled weed and I had beer that wasn't in the case, which is considered open alcohol. I ended up with two minor tickets which totalled $500, when in reality I should have got a DUI and my license suspended for 3 years and forced to go to AA.
Last fall I was drinking with a couple friends when my parents called me and asked if I could pick up another family member and bring them over, right before I got to there house I got a flat tire, a guy came over to see if I needed help and instantly smelt booze on my breath, he then proceeded to get me to call my parents for them to come pick me up or else he was going to call the police, again I should have ended up with a DUI.
Now I hardly drive, ill skate/bike or bus as much as possible, I only drive when I really need to and haven't gotten behind the wheel after 1 drink in almost a year. Earlier this summer two of my friends were driving home and got hit by a drunk driver who left them for dead, one was in a coma for a couple days, had internal bleeding and a punctured lung. The other fractured his skull and his face went into the windshield causing him to have multiple reconstructive surgeries on his face. I'm glad I finally learnt my lesson, because I would never want to hurt someone else or my self, when it is so easily avoidable by calling a sober friend or getting a cab. As someone said, if I can spend $20 on a bottle of liquor then I can spend 20 on a safe ride home
