I am wondering if these guys are able to be on time at all. Anyway, I wouldn't: it would take me too long to calculate all this stuff:
"Say you want to cross the street, but a car is coming down the street, although it is some distance away. You know how fast you can walk or run across the street. Having learned about 1-D general motion, you could decide whether it is safe to start across the street by applying that model: estimate the speed of the car, integrate to find its position vs. time, solve for the time it will take to reach your position; then use the model again to calculate how long it will take you to get safely across the street; then proceeding if this time is shorter than the length of time before the car reaches your position."
