cable can run it faster than any telco can and only when it makes sense to do so.
If you want to see fiber faster than what they're gonna give it i suggest you start building your own FTTH network. Also the HFC networks can and will do more bandwdith than U-Verse or any other Telco network that's not FTTH. And if FTTH was the way to go Cablevision would have done that instead of deploying D3. By the way which is faster than FiOS.
