Thats super annoying, they just changed the intersection near my house to now be a 4 way stop, instead of 2 way, and the confusion of people is beyond ridiculous for such a simple concept.
It reminds me of an ant that gets it's path disrupted.
The person's usual routine is disrupted, and if they don't know how to quickly adapt, they'll get confused. The adaptation of an ant is to find a way around that disruption and back onto the path.
A person should be able to quickly adapt and understand.
It's the routine of a person that is changes. And I'd they don't like to deal with change, or can't handle change, then they'll have a harder time adapting. I have no idea how or why people just suddenly become dumbfounded when change to their routine suddenly occurs.
If you read the signs on the roads, you would know what is coming up ahead. If you know the rules of driving and what to do in these situations, you can adapt. But, not many people know these rules, and what to do when in these situations that you run into while driving on the road.
Driving Education needs to make a come back in Schools, because over here, people just dont know how to handle situations or why you can't just suddenly stop and make a U-turn in the middle of the street...
Or why you need to use your blinker. I sometimes wish I had a bumper car so when someone doesn't use it and decided to suddenly turn, I could hit them and say, "I didn't know you where turning, I didn't see no blinker."
