They've showed you robot cheetahs that can run over 15 MPH, mechanical pack mules and now Boston Dynamics is back to blow your mind once again with a new RC car they are developing. What looks at first glance like a prototype of that flip car you drove in the 90's is actually a souped up toy capable of jumping 30 feet in the air! Hopefully we see some of these babies on the public market soon. I imagine you could pull off some pretty sick stunts with these.
By the way the only time you can appropriately use "sick" as a slang term outside of the 90's is when referring to toy stunt cars, the X-games, and skateboarders in a condescending manner.
