Is it necessary to downshift to first gear every time when parking?

[DelLouis]

It is necessary to downshift to first gear every time when parking. Here are the specific reasons for downshifting to first gear: 1. Reason one: First gear provides the maximum torque, which is most suitable for moving a stationary car. However, on special road surfaces such as icy, snowy, or muddy slippery roads, second gear can be used for starting to prevent excessive torque that could cause wheel spin and make the wheels sink deeper. 2. Reason two: Generally, to save fuel, the idle speed of a car's engine is set relatively low. In this case, if second gear is used for starting, the torque would be insufficient. With excellent clutch and throttle coordination, some car models can still start, but it would be very slow, with sluggish acceleration, and a slight misstep could lead to stalling.
