civilian vehicles would be things such as trucks. go to bnet. they have a few screenies of noble six in a pickup. Ford F-150 Model 2554 FTW?
Yeah i would think the civilian trucks would get owned faster though. Say they drive faster cause their not armored like the warthog, but since its a civilian it can't take oh say a brute shot for instance.
Vehicles will hopefully be faster in Reach because if you think about the top speed of the abrams tank being somewhere around 60mph with a transmission override, the scorpion is like a slug.
If the vehicles are placeable in Forge, this brings new things to racing that will hopefully rejuvenate the section as it has been dead for a while. Forklift racing FTW? I hope there's a semi somewhere I can drive. That would make my day, road raging in a semi running over Elites and Grunts.
