What is that ONE car in your life?

Driving in Delhi for almost a decade, I have figured there is bound to be traffic at some spots, regardless of the time or the day.

However, sometimes some highways that are supposed to be a smooth transition also have traffic.

After dragging through the super-slow traffic, there is always a pattern in such unexpected traffic jams:

One car or one truck was stuck somewhere, leading to the long jam.

What is the one thing you are stuck in right now, that is leading to a backlog of something that is important to you?
