OK. But it's essentially the same concept. Just that auto hold will go a step further and apply the park brake to hold the car in position indefinitely rather than just for a few seconds.

There have been many deaths over the years where drivers forgot to engage the park brake, then stepped out and got run over by their own vehicle. Including, sadly, Star Trek actor Anton Yelchin. If his car had had Auto Hold then he would very likely still be alive today.

The only scenario where this could have a negative effect on safety is where you, the driver, were used to driving a car with the feature but got surprised by its absence when driving an old car. But as I facetiously illustrated in the post above, this is not a valid argument against new safety features. Any accidents that this scenario might cause are far outweighed by all the ones that will be prevented in the long run.
