I know about Pakistan because I lived there for more than 23 years.
Now coming back to reality - you can look through your rosy glasses that you are beating the system and driving a car that is "osum cheap" to drive around and to service it cost you less than 2 tankfuls of petrol.
Reality is that - would you spend money to maintain it properly? probably not, most Pakistani cars are "hammered to fix" with pattern parts or used scrap parts. It may make the thing work for a few kms but it will not be measurable for service.
just like you go buy a home A/C, your technician comes over, installs it without vacuuming the lineset and pays no attention to the superheat or subcooling, nitto tapes the wiring and goes on his merry way after you pay "the low cost of installation"
the result is that you pay through the nose for high electric bills and stupid problems of overloading when the climate is hot.
Who is to blame?
The A/C manufacturer
The customer
The A/C tech
In your car's case when your battery bank falters - you probably would want to unload it from your ownership which wont happen because of that annoying battery fault, just like people asking for cheap solutions for air bag repair.
p.s. the insurance bit was for US dealerships who have to buy shop insurance for mechanics who can get injured while working. Its not required in Pakistan because human beings sell for Rs 100/piece there. You might have not seen a high current injury - it doesnt mean its non-existant.
