Will the Car Maintain a Constant Speed Without Pressing the Accelerator?
2 Answers
Not pressing the accelerator will not maintain a constant speed. Here are methods to maintain a constant speed while driving: Cruise Control: When driving, one important point to know is that cruise control can be used on long-distance trips when road conditions are good. Determine Speed Based on Weather and Road Conditions: When driving, if you intend to maintain a constant speed, it's essential to have a good understanding of the road conditions. In poor weather conditions, it's important to drive at a slower speed. Keep Speed Within a Certain Range: When driving, if your gear is in good condition, you can maintain a certain speed, keeping it within a general range to achieve constant speed driving.
After driving for so many years, I can honestly say that on flat roads, the car won't maintain a constant speed without pressing the accelerator. You'll feel the speed gradually decreasing, mainly due to factors like wind resistance and tire rolling resistance dragging it down. Plus, the engine absorbs energy when idling, making the car slow down as if being pulled back. On downhill slopes, it might accelerate or maintain speed for a while, but on straight roads, it's just not possible. I once tried it on the highway—letting go of the accelerator for less than half a minute, and the speed dropped from 100 to just over 80, which really startled me. For everyday driving, it's best to adjust the accelerator constantly rather than expecting the car to maintain speed on its own—it's both safer and more fuel-efficient. I often advise friends to practice their road feel more; they'll gradually get used to it.
