My cousin killed himself and his best friend by driving drunk. He decided 12 beers was enough but he could see straight (haha right) about 1/2 mi from the bar his truck was found slammed into a light pole, both people thrown out of the windshield and about 50 ft away (or my cousin was, I dunno about the other guy) no belts or anything. Sad yes but as much shit as he was doing I'm surprised it took this long for him to kill himself. I know that's mean esp since it was my cousin but if you knew him you'd understand my reasoning.
As for sleep deprivation, I have two. One was me and friend driving to portland from seattle, roughly a 4-5 hour drive. We headed south around midnight, mistake one, but this was a spontaneous thing cuz the races were crappy so we headed to portland. We got about 3/4 there and he had decided he was too tired to drive and we parked at a rest stop just off the highway. Only once we got there neither of us were falling asleep so we got some coffee and headed toward portland again. We get there no problems wide awake thanks to that coffee (I swear whoever made it made it 5x as strong as it should be) We start heading home cuz it's 4:30 in the morning and my bed sounds SO comfortable right then. I'm pretty much falling asleep every 10 minutes and man those straight aways just knocked my ass out. Seeing how tired I am I tell my friend hey let's park and sleep, we're both tired and you know driving isn't all too safe. So we do and once again we end up awake there. So we did the same thing we did last time we were at a rest stop, got some coffee and took off. All I remember is passing Kelso, Wa and next thing I know we're about 50 mi away from that and my friend nodded off and I started hitting him to wake him up. This went on for like 2 hours, I'd nod off, then wake up and see him nodding off, then I'd hit him and so on. Well the last tme I nodded off he did at the same time and we both wake up inches from the barrior on his side, if he woke up not 2 seconds later we would have hit that going 80. That managed to keep us awake til we got to my house then we both crashed til 4pm in which my mom woke us up asking if we'd like breakfast and "where the hell were you two all damn night??"
Second one is long too so I'll cut it to this: 4am, eastern Wa, coyote got paralyzed for staring at the headlights too long.
