However, on page 171 it clearly states (emphasis added),
QUOTE
"If an attack is made against passengers, make a normal Attack Test, but the passengers are always considered to be under Good Cover (though the Blind Fire modifer may apply to the attacker as the situation dictates.) Passengers attempting to defend an attack inside a vehicle suffer a –2 dice pool modifier to their dodge, since they are somewhat limited in movement. Additionally, the passengers gain protection from the vehicle’s chassis, adding the Armor of the vehicle to any personal armor the characters are wearing."
So... table says +3 (inside a moving vehicle). Not sure if that is including Good Cover or not, so maybe it's actually a +7.
But the description says +4 (good cover) -2 (limited movement) = +2, along with bonuses to the subsequent damage resistance test.
+3... +7... +2... Which is right?
