I'm not willing to try it, because:
1) I honestly can't see that it's advantageous.
2) This belief is re-enforced by the fact that the police will try and do you for Without Due Care and Attention if they see you.
3) I haven't got any sliders on my leather trousers and really don't fancy having a big whole in the knee.
4) I value my kneecaps.
5) I'm fast enough baby!
