Cold Start

You are used to starting your vehicle in a hurry.
Prerequisites: Vehicle proficiency of choice
Benefit: This allows the character to start the vehicle in the same action that he mounts it on a successful Drive check (DC 15). For example, mounting and starting a motorcycle can be done as a move-equivalent action. A roll of 1 on the Drive check means that the vehicle has stalled and will require an additional action to start.

Exotic Weapon Proficiency: Vehicle

You know how to use a vehicle as a weapon, such as ramming and charging.
Prerequisite: Base attack bonus +1 or higher, proficiency with chosen vehicle.
Benefit: The character makes attack rolls with the weapon normally.
Normal: A character who uses a vehicle as a ramming weapon, or the like, without being proficient with it suffers a -4 penalty on bull rushes or charging attack rolls, in addition to any driving penalties.

Lethal Shot

You know how to get the attention of those you hit with a ranged attack.
Prerequisite: Proficient with weapon, Point Blank Shot, base attack bonus 4+
Benefit: After a successful critical attack, the character may choose to reroll any 1s on a damage roll he just made. The second result on these dice must be taken. This ability may be used only once per damage roll.
Special: Entities that are immune to criticals, such as certain Conversions, do not suffer this additional damage.
