Was the car electric? I've had a close call with a silent electric car which would have been my fault. The scenario goes like this: I'm saying goodbye to Joe and about to cross the street and notice there is no traffic around. I realize as I'm about to leave Joe, I forgot to mention something, so I turn back to him and say "By the way, blah blah", and with that, I then step off the curb onto the street without checking for oncoming traffic again, probably thinking about some chore I have to get done when I get home. If I heard cars, I would instinctually check again, but the silent electric mode does not allow for this. I'd be interested in any studies about this: how much more often do pedestrian-at-fault collisions occur in silent electric mode?
