How do you send a love note to space? By writing it very, very large on the Earth.

Houston teenager Stephanie has a dad who travels for work — to the International Space Station. So when she wanted to write him a note letting him know how much she loves him, it had to be big: Like, written by several cars on a city-sized piece of land big. That's where Hyundai came in to help Stephanie out.

Let's get the cynical part out of the way — yes, this video was made as a publicity stunt to promote the new Hyundai Genesis. But it's also a genuinely sweet gesture and a pretty cool engineering feat. In fact, it broke the Guinness World Record for "the largest tire track image."
