I just tried this myself and can't replicate on a 2019 i7 running Big Sur. I wonder if it's related to the number of Wifi networks in range (mine is the only one)... Also, the Apple Maps thing didn't seem to change anything for me, either.
Environment can have huge impact on this. With a larger number of devices, there could be more collisions, increasing traffic more than linearly, and then in case of scanning traffic, the modulation used would likely be the lowest available which means the packets take up a lot of wall clock time. So a broadcast storm with collisions, retries, at the lowest bitrate = brief outage.
How many saved wireless networks do you have?
