If there’s one thing that Korea should built that is a lot of parking area for cars. Cars are enormous here so you will not be surprised if you will find them park in the streets that can cause delayed to some people. Especially if there are some drivers who don’t know the right way to get in and to get out.
As you can see the street could only be used for one car because the other half is already used as car park. So you need to be careful while walking in the streets you may never know what will happen if the driver is busy on his phone.
