move the most
go the fastest
act immediately
Whereas in reality, sometimes we just need to identify the main obstacle to move.
This applies to puzzles, logic, organization, and even everyday life. Sometimes, a small change in the right place can solve a problem that seemed very complicated.
The final answer
So, to summarize the logic:
several cars are completely blocked
some can move but don’t change the situation
only one car can reverse and free several other cars
this car is at the center of the blockage
The correct answer is therefore: car number 4.
