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

The starter motor is build for this additional usage with more durable components. The mechanism is also only engaged when this can be safely done, so on a warm and properly lubricated engine with a full battery, otherwise the system will simply keep the engine running.
