I.e. using that bandwidth, you can consume it in 2.22 hours. So you that's how long they expect you to use Internet in a month? Comcast are smoking something very unhealthy.
This is not news, sadly, and is pretty common for telcom oligopolies around the world. Consumer apathy is a real problem: people know Comcast and have 'no reason' to switch, so Comcast can do what they like and people perceive it as normal.
The only solution is for voters to get their act together and demand taxpayer funded network infrastructure and treat it like a utility. It makes no sense for 10 different companies to run fiber to every residence.
When I lived in Silicon Valley, it was barely better, I could chose from Comcast or Sonic Fusion DSL. I tried Sonic for a while, but my distance from the CO limited my speed (and maybe line quality) to around 8mbit/sec.
