I would absolutely panic, even if going 20 I'd still SLAM the breaks... hopefully the person behind me hits theirs fast enough (as they can't see the thing it'll be delayed reaction AFTER I hit mine) and doesn't smash into me... I 100% agree with the sentiment... for the love of pete slow your tail down... but I think this likely will result in an incredibly primal reaction in people... you need to THINK when driving, not just go on animal protective instinct. Overall I'm thinking this idea could be a disaster... I guarantee you if I heard one of those things was on X street I would avoid it... because even knowing it's coming I'd still jump... just like a scary movie, you KNOW something is fixing to pop out at you... still jump. *shrug* that's me anyways.
