Most drivers who own cars with built-in GPS systems use phones for directions
Semi unrelated question: Am I the only one who wished navigation apps allowed more precise control of route complexity?<p>Just a slider that goes between "minimum number of turns" and "most efficient" would be nice.  Optimizing a route for complexity vs efficiency is a very important consideration when planning a route.  A way to do that in a navigation app would be really nice. I appreciate the intention but taking four extra turns and a one way street or two to save one minute when going somewhere that's one turn off a main road is rarely a good idea.  If I'm driving rural state highways for three hours I'd much prefer to go 150mi on two roads than go 120mi on ten roads.
