Why is this on serious /k?

In any case, whether there is element of brake failure or not; driver is still at fault for speeding in the first place. Holding nearly 40 passengers is like you are holding 40 eggs in a basket without any egg holder, and running back to home, hoping that when you reach home all the 40 eggs are still in place.

This wouldn't have happened if the driver is not speeding and just casually crusing at normal speed. The fastest you can cut is just between 3~10mins, it's just not worth it to compensate with everyone's safety.
