Oh man! I would love for any mapping app to notice that I always exit the Dallas North Tollway at Plano Parkway rather than Park Boulevard, because they're very close, but the Plano Parkway exit is free. I do the same thing when it wants me to merge onto the President George Bush Turnpike and immediately take the Midway Road exit. Again, Plano Parkway means one more stoplight (or two, in the case of Midway), but is a free exit. I do it over and over and over again, and yet every mapping app insists that I save a couple of seconds at the expense of 60 cents. Or maybe spend a few seconds extra at the expense of 60 seconds, depending on how luck or unlucky I am with the traffic signals.
In general, I'd love it if mapping apps wouldn't just say "this route includes tolls," but rather "this route includes tolls of $5.10" or however much, so I could decide whether saving 11 minutes is worth it.
But at least I wish they would notice that I always, always exist at Plano Parkway.
