You may see spikes north of 100Mbps, but nothing consistent. I have first-hand experience with operating an ISP and I am familiar with residential usage patterns, etc. There are of course always outliers, people who excessively torrent, people who are infected with malware that consumes bandwidth, etc.
My household is all streaming, we have Peloton, we game, we stream music, etc. We hardly ever (if ever) average >100Mbps.
