A few weekends ago, I did a 22-hour road trip in a car that had a built-in WiFi hotspot. It was fantastic, but what if you can't afford a $100,000+ Audi RS7? Some Redditors figured out a way to get WiFi on the road for free.

This pic was posted by summgunn with the caption, "We're on a road trip to Vancouver, and we've had Wi-Fi for the past 100 miles thanks to cruise control and this big fella." So, all you have to do is drive next to a long-distance bus, which pretty much all ooze WiFi these days. Public WiFi isn't the safest thing in the world, and neither is driving next to a bus, but hey, it's free!
