When Surrounded By Stronger Vehicles, Go on Foot
This may sound counter-intuitive, but trust me on this one. When you’re in a car battle with multiple vehicles, and it doesn’t look like it’s going to go your way, get out. Mad Max may be mostly about your sweet ride, but it also has a pretty brutal combat system that can decimate opponents just as well as any vehicle. Now you may be thinking “but they’ll just run me over,” and that’s understandable, but the truth of the matter is that they won’t last as long you pay attention.
Enemy vehicles will try to seize the opportunity by ramming into your fleshy body, but they’re easy to dodge, After a try or two they will get out of their vehicles and then you can use Mad Max‘s impressive fisticuffs to deal some justice on your own terms. The AI will not take full advantage for some reason, so you may as well beat them to a bloody pulp.
You can then destroy their cars at your leisure since they can’t move without their drivers.
