You'd think "next to Sal's general store" would work, especially given how prevalent that approach is. In fact, through our research, even for folks working the same delivery area day after day, they consistently fail with these sorts of landmarks. I used to say I lived "next to the vegetable stand on XYZ Rd, across from ABC Apartments" - very visible, clear landmarks which turns out most drivers could never use successfully because they usually called me being lost. You could try NLP on it to then lookup in a db like OkHi's, but these text-based directions definitely proved to be suboptimal when consumed by a human drivers such that companies were actively seeking a better way for their deliveries (and, importantly, were even willing to pay).
