Nah I think there&#x27;s always a little bit of fear about that 10% of the time. Humans are unpredictable- what if they don&#x27;t see you until it&#x27;s too late. What if they want to give you a &quot;scare&quot; and screech to a halt right at your feet- and what if they get the distance wrong and wind up hitting you. Robot cars on the other hand, while they might fail on a rare occasion, will have very predictable behavior.<p>When you walk up to a doorman, you make eye contact and look for him to open the door. When you walk up to an automatic door, you have been trained to know it will open for you.<p>Run an experiment with a bad doorman who doesn&#x27;t open doors, and an automatic door that doesn&#x27;t open, and you&#x27;ll have a lot more people running into the automatic door.
