Topic History of: Insulation on low side pipe beneficial ?

ardvark11 There has been quite a bit of discussion with my fellow tech friends as to putting insulation on the low side piping in an auto a/c system.
Some say it is beneficial in insulating the refrigerant from the high temps in the engine compartment, particularly in hot climates, and claim a lowered vent temp of 4 degrees or more.
I say it won't have much of an effect if any. I argue that if it did the car industry would have adopted it.
Also, I am having trouble remembering if I had seen any insulation in the past on older cars with R12. Was this ever a practice? I know in home units insulation is primarily used to prevent humid air from reaching the pipes causing excess condensation.
