I still have my Thomas Guide from the 90s in my car. Looks like Thomas Guides are limited to LA and San Diego only nowadays, but it's not going away soon: "California state legislation says that every police and fire vehicle must have a Thomas Guide on board. Fire roads often aren’t on GPS, and ambulances can’t get lost, as every second could be life-saving. They often buy laminated copies too, as they get so beat up.” (https://www.latimes.com/entertainment-arts/story/2021-12-07/...)
