Why is cruise control a poor choice on snowy or icy roads?
- A.Cruise control is required on snow
- B.It can maintain throttle or react in ways that break traction, and it encourages a fixed speed when conditions demand constant adjustment
- C.It improves traction by holding speed
- D.It only affects fuel economy
Correct answer
B. It can maintain throttle or react in ways that break traction, and it encourages a fixed speed when conditions demand constant adjustment
Why
On low-grip surfaces the driver needs instant, subtle control of throttle and speed for every bridge, patch, and gust. Cruise control removes that feel and can keep power applied at the moment the drive wheels begin to slip.
