BGP path selection does not route based on link utilization.
What you define as a "non optimal route" isn't what BGP defines as a non optimal route. An ISP can't just send all their customer traffic through any foreign network they choose. The peering location happens to be the "best" path available to Netflix and it won't change until Comcast gets off their high horse and installs Netflix's free caching servers on their network.
