I had a dream last night where I was travelling somewhere in the United States. I hate driving (in real life, and in my dream), so I was worried when I discovered that I would have to merge onto a big-ass highway which I saw on my map. However, when I got there, I saw that it was not quite a traditional highway. Instead of driving, you park at the base of a giant tower. You then take an elevator to the top, and there, you are given a piece of wood that looks sort of like a cross between a skateboard and a luge. Then you slide down this giant rubber ramp on the board. It had many lanes, you could go as fast as you want, and even if you fall off your board, it's ok because you're landing on rubber. There are ramps going both ways, so you can get wherever you need to go. It was much much funner than driving on a regular highway.
I think they should implement these in real life. The only problem is, how do you get your car back from the parking lot at the tower? My brain didn't think of that detail. Please try harder next time, brain.
