I’ll start with last point first. Square area is what the OP image referenced (length X width of space taken).
So if it’s wrong for me to use it then it’s wrong for the op too.
Cars gotta be parked… People have garages and carparks exist. We seen to manage that fine.
And for for done people with disabilities cars are the only way.
I’m short on time so I’ll make this quick… As much as you can drag up edge cases where cars are bad, I could do the same about bikes… But the difference between the morons here and I, is that I’m not trying hard to shit on one mode of transport over another.
It might surprise you but for the most part cars and bikes co exist fine.
