Yes, that and may some BPG looking-glass.
I'm not a routing expert, but AFAIK, you do peering mostly at
peering-locations ("meeting-rooms", internet-exchanges).
At least, that's what we do here in Europe. You have a fast leased line
to such a peering-location and then you can "peer" with everybody you
like and have a low hop-count to that ISP.

Well, peering should improve bandwidth and latency. Because local
bandwidth should be cheaper to get than international bandwidth.
