Don't understand the risk.
Believe the risk is low in the traffic environment I will drive in.
Panic when my plan fails.
Don't want to leave my car.
Don't want to waist money on a taxi.
Don't want to bother anyone for a ride.
I believe I have waited long enough after my last drink.
Afraid i will be labeled as an Alcoholic if I get a ride from someone.
I wouldn't; it is an unacceptable risk.
