Several years back, my mom was hit by a driver, was passed out drunk behind the wheel of someone else's car he "borrowed". Luckily, it was in the middle of the night, so when her car was thrown into the middle of the intersection, she wasn't plowed by oncoming traffic (she got hit at a red light at one of the busiest intersections around here). It totaled her car, and left her with excruciating back pains, which she still has to this day. Sadly, the guy got off with just a ticket and a few days in county jail, despite it being his fourth time in court with a DUI.
I also remember a year or two back, right after my sister had her baby, she hit up one of the local bars to celebrate finally being able to drink after not being able to for the longest time. She ended up getting trashed, driving home, got picked up and a received huge ticket, which caused a chain of events including losing her job and then her home after she couldn't afford to pay the bills.
She claims to this day, that it wasn't her fault as she couldn't remember anything from that night, and that everyone makes DUI's out to be a bigger deal than they are. Doesn't even acknowledge the fact she lost her job or home as an effect of it, and could've lost her life and left her daughter without memories of her mother.
After seeing how from these two experiences, and several others with friends and other family members, led to the person who was drunk getting off, basically scot free (or in the case of my sister: getting off scot free in her eyes), I believe punishment for those who drive drunk should be much harsher than it is, or at least much harsher here in Florida. I understand that drinking can cloud your judgement, but so many people (at least around here) are repeat offenders, or get off the first time with little in the way of punishment, and don't see it as being that big of a deal.
