I drink them occasionally. I especially drink them when I'm doing a cross country drive. A Rock Star Zero Carb and eating sun flower seeds will keep me going for a long time. I know it isn't the best stuff for you, but neither is falling asleep at the wheel and crashing. I've been drinking them more than normal lately, as it's duck season and I've had a lot of 3:30 Am wakeups to head out to go hunting. I have a 1:45 minute drive to my club, and a Rock Star helps get the day started sometimes when I'm running low on energy. Once I get done with hunting, I'll usually take a nap before driving back home, and that's a lot healthier than pounding down an energy drink.
