A feature I wish maps and nav apps had: “kill 10 minutes”. I’m often early and sometimes I just want to drive around for an extra 10 mins. Or I want to go the long way and add some time because I know I’ll be early. I obviously can just sit there early, or drive some more myself, but would be nice to know that I could add a quick 10 (or whatever) minute loop and end up back on time.
