My solution would be to politely refuse to do the dangerous thing, say why it's dangerous, and say that if he or she doesn't like my choice then he or she should write me a ticket for whatever law I'm breaking. And if he or she doesn't want to write a ticket, I'd ask him or her to either let me go on my way, or charge me with something criminal and arrest me (seeing as those are my two safest options). I'd be as calm as possible, and probably even politely thank the officer for doing his or her job as he or she understands it to be.
<br><br>Though, in a real situation, I'd be more likely to create a scene and get assaulted by the officer - given that this is what happened already to me in a similar situation... (Though I'm getting better!)<br>
<br>I'll also suggest learning the Non-Violent Communication techniques taught by Marshal Rosenberg, and, somewhat nonintuitively, I'd recommend the Effective Communication techniques taught by Fred Kofman in his book Conscious Bussiness. Both techniques focus on leading a conversation in a more effective, positive, and productive direction, even in difficult situations.
