unrealistic of real-world driving conditions.

2700 RPM while not moving is a significantly different situation compared to 2700 RPM while accelerating in any gear, 2700 RPM while holding a speed in any gear and 2700 RPM while engine braking in any gear.

the load placed upon the engine is different in all of those situations.
