The most stupid mechanics in the game (Mad Max)

In Mad Max there are quite a few absolutely stupid mechanic, whether it be breaking down after couple of strokes steel wrenches, the need to collect water/to drink/to pour the gasoline/banks have the same and open the same door to collect scrap metal with horribly long animation, being able to quickly move with a stolen car chosen in the fortress, the cartridge chamber into which fit a large-caliber sniper bullets more than the shotgun, broken fuel system (two passing gas up the car twice - in the prologue, although he is guilty, thanks to the fuel tank)..

But the stupid created by the broken farmer-redneck in all of Avalanche Studios, in my opinion, this is a minefield.
More specifically the need to travel the entire map in a slow, non-armed machine without the possibility of rapid movement and neutralize 90 min with disgustingly long animation and the ability to explode, stepped on an antitank mine character (the guaranteed loss of progress, because neutralized minefields are not saved until you return to base).
And there is such a need, if you want to platinum/best v8 engine, a harpoon and caps.

And what do you think is the most stupid mechanic in Mad Max?
