While this could be conspiracy, arguing bus drivers don’t get lost, even when they are professional ones is naive.
2 Completely professional and well trained airbus pilots flew a completely functioning (with the exception of a blocked air speed indicator) and brand new plane into the ocean just a few years ago. Believing something is NOT POSSIBLE when humans are involved is naive.
Was the driver lost, or just off track? GPS also may not be of much good due to street closures and such. Making one bad turn can screw you up in a downtown area under normal circumstances (one way streets). I wouldn’t be too quick to holler conspiracy and demand the guys head on a platter
