But in a very similar vein of the origonal post, you acctually dont know what your home smells like because after a few days of living somewhere your brain starts to block out lots of unneccessary sensory input.
So you will never really know if your place has ‘a smell’ unless someone tells you, plus if your friends and family are being polite they probably still wont tell you if its a (slightly) unpleasant smell.

This is a perfectly normal and reasonable paranoid thought i have often.

Are you talking about the CVT oil pump? Or have some manufacturers started doing doing this on the engine oil pump?

Edit:
Well i looked it up myself and it seems that newer cars, especially more expensive cars have addresed the wear issues by upgrading the crankshaft bearing, hardened internal components, upgraded altenator and a specific type of battery for this use. (No mention of electric oil pump motors for average cars)

You also need to replace the (more expensive) battery every 3-5 years, so the cost is still comong back to you. Higher quality upgraded components + the more expensive and often replaced battery will all end up back on your pocket, like i said the system probably isnt worth the cost of the fuel and emissions savings.

And if you have an older car with this function, then you also have the component wear issues, see the video i mentioned in the first comment: https://www.youtube.com/watch?v=qu8cJ2t_ja8&pp=ygUpYXV0byBzdG9wIHN0YXJ0IGVuZ2luZSB3ZWFyIHRlc3RlZCBnZXJtYW4%3D

If your talking about the auto stop/start that happened when you push the brake down at the lights you should 100% disable this.
They implemented it thinking it would be great that you would be not burning fuel and emissions for 30s while the lights were red but in reality what happens is that as soon as the engine stops your oil pressure drops, then your restarting with no oil in the cylinder and that causes an extreme amount of wear on your piston rings and other components. I dont remember the exact figure but starting and stopping while the oil pressure is low is responsible for like ~90% of engine wear.
Depending on how many lights you encounter you could be doing exponentially more basically cold starts and your going to need to service your car much more often, replace the oil and filter, replace other components that wear (+ costs of increased servicing) just to save a couple minutes of idling emissions and fuel. I can tell you which is much worse for the environment.
There is a german channel on youtube that literally did this as a lab test with a real engine to show how much extra wear was happening to your engine. The system was a ‘good on paper’ idea but they overlooked some key factors i think.
