Walking is not often from-A-to-B traffic. Walking is part of human behaviour, a way to immerse and express with regard to themselves and their surroundings. Similarly to how humans pause to think while they're speaking―or writing, as I am now―they also tend to pause to wonder while they're walking. Humans aren't robots and a sidewalk, a cafe, or a department store are good places to exhibit this natural behaviour. That should not come as a surprise to anyone and people who need to rush fast through will simply dodge any such obstacles. And people blocking entryways get soon nudged to the side by the stream of people. It's not much different from that when a human is driving. The conditions do dictate some limits to how the driver can wander about (you can only mostly go straight on a highway) but everyone will stop to think something at times and maybe happens to slow down or slowly steer left/right until they refocus on driving again. However, on the road, this behaviour is very irritating for those who are in their from-A-to-B mode because, unlike in a busy railway station where they can just snake through the crowd, with the worst case of gently bumping into bypassers while at that, they can not easily go around the slower drivers in busy traffic. Driving is basically monotonic robot work, or should be. It's not a natural way of being that lends to distracted behaviour as walking about does.
