So in the Lockdown game I'm running, I'm thinking about giving the party some sort of an escort run that spans the city, with them be waylayed by other factions en route and engaging in a Mad Max - style road war. I'm talking custom vehicles (assuming gangers) and lots of stats for different sorts of specialized grunts, people hanging off of trucks, melee combat happening on rooftops, people trying to outmanuever each other, and other factions possibly joining the chase when they pass, for example, an entrance to the catacombs.
Thing is, I'm not too familiar with the vehicular combat rules, so here is my questions. Is it possible to prep for something like this while still holding down a full time job and a social life?
