Changes in Greyhound business practices jeopardize the already-limited options for cross-country travel by people in the USA who don’t have, or don’t chose to show, government-issued ID credentials.
For local transportation, undocumented people who want or need to travel further and/or faster than they can walk can ride bicycles (although there have been proposals in some jurisdictions to require registration of bicycles and/or bicyclists), or use public mass transit (where it exists, and where fares can be paid anonymously in cash, which isn’t the case with some cashless transit fare payment schemes).
Long-distance travel options for people without papers are even more limited. Policies adopted by airlines and Amtrak, combined with ID requirements for drivers of private motor vehicles, have left long-distance bus companies as the carriers of last resort for long-distance travel by undocumented people.
The options for the undocumented get even narrower when one starts looking at specific routes. Greyhound is the only company providing scheduled transcontinental bus service, a truly national route system, or any intercity bus service to many destinations in the USA.
That makes Greyhound’s route system and ID policies, or the lack of any Greyhound policy conditioning domestic US travel on possession or display of government-issued ID, of paramount importance to anyone who wants to move about the US without showing ID.
