It's silly that you think that this is anything to do with being a person. Why can't I walk in the middle of the road, you know, like a person? It's just such a bad faith argument.
The context was cycling on rush hour Washington Boulevard, which isn't absurd if it's the easiest route to your destination, any more than walking down a road is absurd if you don't have an alternative.
The context (sigh) here is that I'm saying "like they're people" is not a good argument. Drivers are also people. It's not an argument. I don't know why the topic keeps drifting off this.
Being a person is a good prima facie argument for being allowed to access public infrastructure. There may be countervailing considerations, but you didn't provide any (other than by apparently suggesting that it was somehow absurd for people to walk on roads).
But I'm not the author of the "like they're people" comment, so I'm not particularly interested in defending that particular line of argument.
