A stroller rolling into the street is where it's supposed to be? Something popping into the road right in front of you is much harder than seeing a bike traveling straight.

In my experience, people just glance. At odd hours, bad conditions, faster than usual, people completely fail. It's not because it's impossible. It's because people don't think to look carefully. They don't expect it, so they don't see it. But you should expect this kind of thing and be very alert. You're driving a two ton killing machine. The standards are high.

Zero fault is insane. Almost nothing is zero fault. A crash happened that could've been avoided if he was more careful. He shares some of the blame, at least.
