My experience AND upbringing is to leave no one behind.

The elderly couple across the street have a lifetime's wisdom & experience in their heads. Their thinking and recommendations are likely to help avoid a disaster while evacuating from a disaster.

The young diver next door has resources and skills to contribute.

I can go on & on. The bottom line is that, I feel, everyone has valuable contributions to add to the group's survival, if bugging out of a neighborhood became necessary.

Yes, I would assist the carless. Extra drivers would also be needed as well as extra guards, worker bees, etc.
