How do Hybrid cars (or any car that ‘cuts off’ when idle) not just blow their starter or have massive wear on the engine?

Question

Basically the title. I was always told most engine damage is done when starting the car, I live in a city and see and hear cars cutting off at every stoplight. How does that not blow the starter or engine?

Answer 1

Starting the car is hard on the engine because after it’s been sitting a while, the oil has all drained out of the cylinder head and valve train, so they run with little to no lubrication at first. Because it takes a while to drain, it’s not a problem at short stops at traffic lights and such, so all you have to be concerned with is the starter itself, and the starters in cars with this feature are said to be more robust than in cars without it.
