Yeah. Never stop if the flow of traffic is ignoring them anyway. If there's a break in the traffic and you are one of the first cars, then stop for them.
The moto rider is a complete idiot too. Anytime you see a car stop on the road, you slow TF down and verify why they are slowing
The pedestrians also must be attentive and if you see something, just run or at least be prepared to dodge something.
