Final answer:
You should not drive if you're angry or excited until you have calmed down, as strong emotions can impair driving decisions and lead to variable speeds.
Step-by-step explanation:
If you're angry or excited you should not drive until you calm down. Emotions can significantly impact driving ability, potentially leading to reckless or impulsive behavior on the road. An equivalent scenario is assuming that you traveled home from a party at a constant rate when your emotions may have sparked a varied driving speed. At first, being mad about having to leave may cause one to drive fast, but upon calming down and considering the risk of police presence, you may slow down to a more socially acceptable speed, such as 80 kilometers per hour. Therefore, it's advisable to wait until you're no longer emotionally charged before driving to ensure your travel is safe and at a consistent speed.
