Final answer:
Frequent sudden stops are least likely to cause increased fuel consumption.
Step-by-step explanation:
Making frequent sudden stops would be LEAST likely to cause increased fuel consumption.
When a car comes to a sudden stop, the kinetic energy of the moving car is converted into heat energy through the braking system. However, this sudden stop does not directly affect fuel consumption as it does not involve the burning of fuel. Therefore, among the given options, increased fuel consumption is least likely to be caused by frequent sudden stops.
