I've heard it used in automobile insurance...insurer provides a temporary clause in the policy, automatically insuring a buyer's vehicle for a period of a few days prior to the buyer before actually adding the coverage of the purchased vehicle.

Think automobiles, air conditioners.

It also does a somewhat poor job of analyzing mileage vs actual expenses on business use of personal automobiles .For example, just because you **CAN** take 179 on a piece of equipment, it doesn't necessarily mean that you should.  

In addition, all expenses related to your automobile such as registration, insurance, and repairs is 100% tax deductible.

However you commute plane, train, bus, automobile use that to educate yourself...TRAVELING UNIVERSITY that is what ZIG ZIGLER calls it.

I also frequent automobile and stereo forums. 

I've turned wrenchs on cars, trucks nd equipment as well as done sales of automobiles, parts, equipment, and services.

Dang, I actually dug all through the regulation for this one because I was curious.For any that are curious....this is found in AR 600-20, para. 4-14c(1)(1)Ongoing business relationships between officers and enlisted personnel, or NCOs and junior enlisted Soldiers.This prohibition does not apply to landlord/tenant relationships or to one-time transactions such as the sale of an automobile or houseThis is an Army reg, so different branches should check their regulations.

What about bank accounts, brokerage accounts, boats, automobiles, high value personal property such as jewelery, etc. that will become part of the probate estate? 

 It will be a long long time before gas powered automobiles and trucks are replaced if that ever even happens.Yes gas stations and automobile service based businesses are a great investment.
