Not necessarily. If I have more than a couple drinks or feel impaired in the slightest bit, I call a cab. Basically I call a cab anytime I go out. But after using a sample breathalyzer, I am sure there have been many times where I unwittingly drove right around a .08-.10. Studies have been extremely inconclusive at best when it comes to that range. I mean 1 stronger than expected margarita with a Mexican meal and you're at that level. Most likely you do not feel much impairment. If you want to steepen drunk driving penalties for habitual offenders, I'm with you. If you want to steepen them on general principle, I want to know what you plan to do for people caught talking on cell phones, eating, texting, applying makeup, etc... This makes you a bad person.
