I was looking to drive from New York, where I work/live, to Toronto for a conference, so I went to Google Maps and inputted the addresses. Google Maps showed me this weird straight line from my office to my destination, heck, flying over water and plowing through mountains and homes.
How was that possible? To go by air.
I didn't want flights, but Google Maps told me a flight would take less time. Not only that, I can book the flight using Google Flight search. A 1.5 hour flight would actually be longer for me than a 7 hour drive because of driving to the airport, going through security, getting to the destination after you land and so forth. It would be a wash, in time.
Here are pictures, I believe this only comes up when using the new Google Maps:
