can you drive a car only on negative

[Julian]

No, you cannot drive a car normally using only a "negative" setting, as this term isn't standard for vehicle operation. If you're referring to selecting a low gear (like 'L' or '1', '2' on an automatic shifter, or a lower gear in a manual), then yes, you can drive, but it's for specific, limited situations, not general use. Driving exclusively in a low gear is inefficient, harmful to the engine, and potentially dangerous.

Using a low gear intentionally increases engine RPM (Revolutions Per Minute) while limiting the vehicle's speed. This technique, called engine braking, is useful for controlling descent on steep hills without overheating the brakes. However, sustained high-RPM operation at normal road speeds causes excessive wear on engine components, drastically reduces fuel efficiency, and can lead to overheating.

For everyday driving, an automatic transmission is designed to shift through its gear range to optimize performance and efficiency. The drive (D) mode handles this automatically. The following table outlines the primary purposes of different gear selector positions versus the incorrect concept of "negative" driving.

Gear Selector Position	Primary Function	Typical RPM Range at 40 mph	Suitable Scenarios
Drive (D)	Normal driving; automatic gear shifting for balance of power and efficiency.	1,500 - 2,500 RPM	Commuting, highway driving, everyday use.
Low (L) / 1 / 2	Provides maximum engine braking or power at low speeds; prevents upshifting.	4,000 - 6,000 RPM	Descending steep grades, towing heavy loads up a hill, slow off-road crawling.
Neutral (N)	Disconnects engine from wheels; no power to wheels.	Idle (e.g., 800 RPM)	Being towed, stopped at a long traffic light (debated practice).
Reverse (R)	Allows the vehicle to move backward.	Varies	Parking, maneuvering in reverse.

Attempting to drive at highway speeds in a low gear would force the engine to operate far beyond its efficient range, potentially triggering warning lights and causing serious mechanical damage. Always use the transmission as intended: 'D' for driving and low gears only for specific, temporary control needs.

You'd basically be redlining the engine the whole time. It's like trying to run a marathon while sprinting flat-out—the engine can't handle that stress for long. You'd watch your fuel gauge drop, hear an awful whining sound, and probably see the temperature warning light flash on. It's a surefire way to turn a reliable car into a pricey repair bill. Stick to 'Drive' for 99% of your driving.

Think of it from the car's perspective. The transmission is designed to keep the engine happy, not screaming. Using a low gear all the time is abusive. It puts immense strain on the pistons, valves, and cooling system. The computer will try to protect itself, but you're forcing it into an unnatural state. It's not what the engineers designed it for. Proper operation is key to a long vehicle life.
