There are indeed commercial and in-house products which use probes and
traffic measurement to influence the BGP decision process.  Watch tarpit
logs for sites that ping every subnet on a regular schedule.  I hope this
doesn't catch on or all the pings may drown out real traffic...

As a general description of Internet routing, I agree it's laughable -- but
the technology does exist.
