What sets us aside from robots, is that we are risk takers by nature, we are constantly making judgements throughout our day, assessing and reassessing situations without even knowing it...making split second decisions. Sometimes we are going to get it wrong. And when we are in a steel box hurtling past other steel boxes or obstacles at any speed above standstill, deaths will result from said decisions. More and more of those steel boxes on the road every year. Road toll will never reduce greatly, let alone be zero. Accept it. As alluded to on other posts, there are other things that kill us, which we can achieve reductions in.
