With the Messages commands you can tell Driver what to say at
certain event. From here you can get ride of the 'Lose the Tail
message'.
Messages are divided in two big categories, the first use Text to
display messages and the second use an index to a Message Bank. I
recommend to use the first categorie because the Text are then
written with the Mission (*.dms) instead of being apart. This
make those missions more portable. (i.e. for the web)
