I rarely drive specifically for the fear of this situation. I don't ever want to kill someone. Never. If this were to occur though, I don't know what I would do... Frankly, I never want to know. Should help noting though, that so long as I drove without intent to harm and that I drove with reasonable care and foresight, both of which I can likely prove with my dash cam, I doubt I could be convicted even If I did claim responsibility. If you were to be given the opportunity to pass any law/bill you'd like in your country regardless of how strange or crazy it is, no questions asked, no ammendments or repeals. What law would you pass?
