The choices aren't simply caps/overages to capacity problems. How about we reduce the advertised speed? If there's a capacity problem, stop increasing the advertised speed options and selling something you apparently can't deliver anyway. Even if I have a 50Mbs or 100Mbs internet connection, most sites and downloads aren't going to go any faster anyway because of bottlenecks at the other end or along the way. It only makes a difference on concurrent connections. If I had a choice between caps/overages and reduced maximum speed, I'd take the reduced speed.
