another idea for places that don't have enough HA slots.

stores and businesses could make a pick up & drop off spot right in front of their building.
- those with a partner/driver could be dropped off right near the main door, then the driver could find a parking place & meet up inside do shopping and then go retrieve the car and load everything back at the pick up/drop off area.

Some of the stores here have a safely lane in front of the store - so that would work as long as you can load up quickly.
