i have been driving my (old) car for 13 yrs. I never use my hand-brake. My ex-gfs do use the hand-brake when they park the car. In taiwan / hong kong, people might use the hand-brake. In US, we do not use brake much. It is because when we park, the car does not move anymore. What is it good to use the hand-brake if someone bumps to your car anyway?
anyhow, if you feel comfortable using the hand-brake, I think it would work for you.
