Couriers use Waze not Google.
Waze gives better routes and is updated for road problems better than Google .
I use Google maps for certain parts of rural routes as you can download offline maps, handy for when there is no signal and Amazon app stops working.
Amazon currently use mapbox which is inferior to its previous provider (can’t remember who) which had offline maps for seamless use when there was no signal. The new mapbox does have offline maps feature only it doesn’t work and hasn’t since it was introduced.
