Sorry, I forgot to mention, their example:
https://en.wikipedia.org/wiki/Drift_velocity#Numerical_example
Similar to Thomas, calculates a drift velocity of 20 micrometers
per second for 1 ampere in a 2mm copper wire.
But the final sentence on that page is interesting:
"By comparison, the Fermi flow velocity of these electrons (which, at
room temperature, can be thought of as their approximate velocity in
the absence of electric current) is around 1570 km/s."
