Living in flat Florida I’ve never felt the need to use the parking brake. Well, maybe once or twice if I happened to park in a steep driveway, but I don’t think I really needed it even then.
Curiosity got the best of me so I asked 8 of my girlfriends who used the emergency brake, and only one uses it every time. The rest of us only use it on a steep hill. So I’m not the only one. None of remembers being told to use it every time in drivers ed either. Lol, maybe it’s an Ohio thing (joke)
That’s why I drive a Toyota
