I have to completely disagree with you foreverme. You are reading way to far into this song, its not an anti-drinking and driving song. This song is about going through a weird stage of life while you are trying to figure out whats important and who you are. Its about not giving a f*k and doing exactly what you want to whether its going out and getting fucked up or whatever it is with a disregard for the consequences. It may be selfish but its something some people go through, and it doesn't sound like you have gone through that.
This song speaks to me like no other lyrics have before. It sums up life right now for me and I know that things will be fine and this isn't a permanent thing.
