Assuming the following stopping distances:

Using figure 6.7 and the data in the table above, explain how the on-board computer would calculate if a car was too close to the vehicle in front and apply the brakes if necessary. [It is not necessary to show all the maths, it is sufficient to explain what would need to be done. However, this could be a class exercise using a spreadsheet or small computer programl.
