There are two options for determining
initiative in vehicle
combat. First, is individual
initiative just as in normal
combat, where each character rolls separately. This is probably the best method if most or all characters are aboard the same vehicle, but it can result in a lot of delayed or readied actions as passengers wait for drivers to perform maneuvers. An alternative is to roll
initiative for each vehicle, using the vehicle's
initiative modifier. This is particularly appropriate when characters are in separate
vehicles, since it allows everyone aboard the same vehicle to act more or less simultaneously.
