I live in an area popular with walkers & bicyclists due to the winding, undulating roads. They often travel against traffic on one-ways in the heart of town(roundabouts and one-way streets) and on the shoulderless two lanes. Anecdote related to TFA:, a couple months back an SUV stopped at a marked crosswalk with ped traffic. I stopped in right lane next to it. When peds cleared it began rolling before I did, and once I commenced it braked hard. I braked, looking for unseen peds and noticed it's nav gear & small uber decal. No additional peds were in crosswalk. There were dozens og people on either sidewalk for an art fair. I wonder if human intervention caused the hard braking or the large amount of data points on the periphery.
