Many more disabled people are disabled in a way that prevents them from driving a car than in ways that prevent them from walking. There is also a huge class of people who are physically capable of driving but legally barred from it.
In fact when I scroll back through your recent comments I find it hard to find any that don't break the site guidelines with some sort of aggressive or nasty edge.
We have to ban accounts that post like this. This is not what HN is for, and destroys what it is for. It has also, unfortunately, been a problem for years:
I'm not going to ban your account right now because you've been here a long time, but if you want to keep posting here then we need you to properly fix this going forward. That means being respectful and curious, and it also means not being irritable, mean, or any of the other things that lead people into the flamewar style. So if you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
