Now I mean:
/v is the command for spawn a vehicle (and a player will be automatically in)
When a player type /v
He will be see: * Sorry, you must be type /v <name>
Let we do as example an infernus.
When a player type /v infernus, he just spawned a infernus and will be automatically in the infernus.
But a player can type:

/v inf
/v infe
/v infer
/v infern
/v infernu
/v infernus

He can type everything for spawn a vehicle but the player need be max type the first three letters.
For spawn the vehicle that he want.

And how can I make the command /v
