e46 318ci bmw drifting with an open diff on a roundabout uk south wales

I have a roundabout near my house which I practice drifting on. I'm getting better and with the open diff it really doesn't help. I will try and get a video of it in daylight, but you can see how sideways I am when the lights shine on the signs. This was on a private industrial estate, at night with no bystanders or other motorists.
