Abstract
A message is received in a vehicle together with a description of a geographic path that the message is to travel along. The vehicle'"'"'s geographic position along the geographic path is determined and a message broadcast time for rebroadcasting the message based on the vehicle'"'"'s geographic position is determined. The message is rebroadcast with the description of the geographic path at the message broadcast time. Many examples and different variations are presented here.
