To avoid the vehicle running during the initial position estimation, driving_log_replyaer plays the bag for a bit and then pause and call the initial pose service if the initial position is given. However, there is a problem that the success of this method is random and if it fails, the simulation will stop indefinitely. Now that PR has added the ability to give the initial value directly, we will change to this method.
