Some motorists are afraid to pick up high speeds.
Such drivers believe that driving at low speed is a guarantee of safety and fuel economy.
But they are not entirely right.
Firstly, under certain circumstances, a vehicle that is “barely moving” can create a dangerous traffic situation.
Secondly, low speed does not at all ensure minimal fuel consumption.
Thirdly, the complete rejection of high speeds has a negative effect on the car and some of its systems. The following difficulties arise:
Continuous driving at low speeds has a negative effect on the cooling system.
The result may be overheating of the power unit.
Driving at low revs can impair engine oil circulation.
In this case, serious problems with the engine will arise.
If you completely abandon high speeds, the pressure on the transmission may increase. As a result, its condition will quickly deteriorate.
Therefore, you don't need to constantly drive at low speeds. However, don't forget about the importance of observing the speed limit, don't exceed the permitted speed and avoid abrupt maneuvers.
For reference
Speed is a vector physical quantity that characterizes the speed of movement and direction of motion of a material point relative to a selected frame of reference.
