The word “commute” took on its modern meaning when trains in the US started running from suburbs to cities in the mid-1800s. Daily travelers got “commuted” (reduced) fares and were referred to as commuters
The stop request cord on a city bus has been in place since the earliest days of mass transit (1662!) and was originally tied around the driver's ankle (since they were outside and had no other way of knowing when people wanted to alight)
Cool! So ‘commuter’ is like ‘frequent flyer’ - reduced fares for frequent work related travel.
I assume there were no points systems or perks though, that would have been hell to keep track of before computers.
