I was cycling on this section of road the other day and had a laugh at the sign to the right which shows a car, cyclist, and pedestrian with the words “Share the road” written underneath.
You’ll notice that both the bike lane and “sidewalk” end just after the sign, leading both cyclists and pedestrians into an uphill, blind turn where aggressive motorists absolutely do not share an inch of that very narrow lane.
“Share the road” is like asking all the kids in the classroom to give their lunch to the class bully.
Most likely the sign is some official’s response to a complaint by a cyclist or pedestrian about nearly dying there.
“We’ll just instruct the cars to be sure not to run them over. Problem solved!”
