Final answer:
e-Pedal and e-Step may not provide sufficient deceleration when a car is accelerating while driving, as these systems are not designed for rapid speed changes or emergency situations that require intense braking.
Step-by-step explanation:
The student is asking about situations where e-Pedal and e-Step, which are technologies related to the control systems in electric or hybrid vehicles, may not be able to decelerate or stop the vehicle effectively. These systems are generally designed to help drivers control their car's speed using primarily the accelerator pedal, enabling some form of regenerative braking and deceleration without needing the brake pedal. However, they may not be sufficient in all circumstances for stopping the vehicle.
Answering the question, e-Pedal and e-Step may not decelerate or stop the vehicle sufficiently when driving a car accelerating while driving. Such scenarios could involve quick speed changes or emergency situations where stronger braking force is required beyond what regenerative braking systems can provide.
