Google can not get it right in LA. Ghost busses are common, either on the app and not there in reality or right in front of you and not there in the app. The times are basically fixed; if it says the buss is 12 mins away, it will still be 12 minutes away 12 minutes later. If there are two routes that can take you down the exact same road to the exact same destination, you will be randomly assigned one route due to all of the above problems and be unable to view any information at all about the other, as if it doesn't exist.
