DOCSIS has a very difficult time providing 100+ Mib/s connections. It's really only possible when the distance to the cabinet is less than 1 km and the number of clients served by that cabinet is less than 50. This is why cable companies are able to offer 300 Mib/s connections in urban areas that have a cabinet for every block, but struggle to deliver 50 Mib/s connections in suburbs where a whole neighborhood must share a single cabinet. The cost of installing enough cabinets to give everyone 100+ Mib/s rapidly approaches the cost of fiber-to-the-premises as population density drops. There is also the issue of the asynchronous nature of DOCSIS. Cable companies must make a trade-off between upstream and downstream bandwith, and tend to assume that people value downstream much more. This is why you see hilarious allocations like 300 Mib/s down and only 5 Mib/s up.
