the woman does this all the time and it annoys the hell out of me. I had to explain to her what a parking brake's job is.
My Mustang has something like this and it's awesome (it's a 6 speed not auto). If I'm on a hill, put it in first and let off the brake, the brakes are still automatically applied for a couple seconds or until I let off the clutch. I used to hate people stopping right on my ass on a hill and I'd have to be doctor lightning feet so I wouldn't roll back into them.
