How long would 100 cars stopped at a traffic light take to all pass the light?

This is a classic estimation problem that requires breaking down the process. We need to consider the time it takes for the first car to start moving and then the time it takes for each subsequent car to start and clear the intersection. Key factors include reaction time, acceleration, the length of the cars and the gaps between them, and the speed at which they travel. A detailed calculation would involve estimating these variables and summing the time for each car to pass the light.
