Good question but Not if its icy or snowy DONNNNTLol, but if its dry and you practice this method then it could help slow you down yes,
But the potential for putting you into a tail spin skid is rather high, like i said unless you practice this in a safe area like a big safeway parking lot or something with no other people or cars around.
Whatever you do dont crank on that thing, light pressure and allow lots of distance in front of you.
That being said, as a last resort and I wont recommend it for the possible danger of the brake locking mechanism catching and causing a rear tires to skid which could cause your car to skid sideways.
But it can be done yes.
Safer if you have a pull handle in the middle between seats so you can keep the release button down.
Not very safe if its a foot brake and you have to have the release pulled while you are driving trying to feather the E-brake.
