I experience this almost everyday. I'm at the bus stop near my place 15 minutes before the time posted and when the time comes, it says it is arriving when there is no bus to be seen. Afterwards, it says it has depearted. This doesn't just happen with one bus it happens with sometimes the next bus. One day I spent more then 30 minutes waiting for a bus. During this time, supposedly about 4 buses came by. I guess I can't see because there was absolutly NO bus that went by. It would be ok if this happened sometimes, but on a regular basis this is unaccpetable. Why pay for GPS if it doesn't work properly.
