Dos and Don't of vehicles

This guy makes some good points but some I think are not really well understood by him.

1: Using the parking brake for example: Yes the vehicle will rely on the parking pawl in an auto vehicle to keep from rolling away on a hill without using the parking brake, but the pawl doesn't really wear out. If it breaks you are in neutral, if it doesn't break you are fine. When he says it adds years to the life of the tranny, that's BS unless you somehow break the pawl and then scrap the tranny.

I use the parking brake religiously but not to prevent transmission wear, more for safety and to protect the pawl from an extreme load that would break it.

2: The not waiting for the vehicle to stop rolling back befoer shifting into drive:
The load change from backing @ 2mph vs stopped is minimal, and easily absorbed by the torque converter which exists for no other reason than to absorb the difference between engine rotational speed and input shaft rotational speed. The load placed on the tranny/torque converter would be tiny compared to even modest acceleration from a stop.


Riding the brakes down a hill: This guy says to not ride them @ light pressure and instead apply and then stop then apply. The total amount of stored energy in your vehicle from it descending from an elevated postion is the same regardless of how you apply your brakes. That energy must go somewhere and that is conversion into heat. Regardless of your braking stratagy that heat will go into your brakes. If you decide to brake hard repeatedly instead of slow gentle brakeing you will just cause rapid heating cycles that likely would be more prone to rotor warping and such. If the guy wasn't a moron he might suggest downshifting.

6: Staring the car the wrong way: He essentially wants the electrical draw reduced. Nothing really wrong with the logic here except the draw from the accessories is minimal compared the draw from the starter. Although true:
Most of the wear on the engine happens when you start the car
this has almost nothing to do with electrical demand. The reduction in electrical draw from turning off low demand electrical loads for several seconds would be like trying to locate the fly shit in a pepper factory.
