3 Mbps/household is right about the lower bound for average Internet usage. It's not optimal, especially going forward, but it's fine for now.
Upping those 2G backhauls to 10G is simple and cheap, however.

Averaging 3 Mbps of usage does not mean the gigabit connection drops down to 0.5% nightly. The key here is for the ISP to have enough excess backhaul to account for the occasional burst above the 3 Mbps average. As long as there is sufficient headroom, nobody will notice the oversubscription.
