Why are these numbers chosen for the default local network? 192.168, not 193.167
Just do not write that this is a standard and throw links to rfc. The nature of this solution is interesting.

Because there are a number of standard addresses designed for local networks. Document describing these addresses .

at least they look nice in binary.

At the time RFC1918 was created, 192.168.xx was the lowest unoccupied range for the C network (/16)

Answer from co-author of RFC1918)))
I saw the IANA address allocation history somewhere. You can see there what was free at the time of preparation of rfc in different classes of networks.
