I don't really understand this. Here is what it says in the book:
"Most vehicles can be used as weapons (to run your target over). It counts as a close combat attack but both attacker and defender roll for DRIVING."
FIRST QUESTION: What if the defender is on foot? They roll for DRIVING? What about rolling MOBILITY instead?
continuing...
"This roll can be combined with the speeding action above, but since the DRIVING Roll will then be an opposed roll, the effectiveness of the speeding might be reduced."
SECOND QUESTION: Aren't both "opposed" rolls? If I'm the defender and I'm "more successful" on the "close combat" thing from the first quote, don't I still just avoid damage? I don't quite understand this.
Thanks!
