Jay Leno's car was street worthy. He even had a stereo in it. We were at Edwards Air Force Base. At something like 150 miles an hour, one of the windows blew out. And they caught that on slow motion. I'm still trying to wrap my head around that. Neil deGrasse Tyson: You're actually limited by the acceleration of gravity. That's it. How fast is it when you shoot a car in the space? Oh, you want to shoot a Tesla Roadster? Yeah, exactly. This guy is the limit. Relativity is the limit, but there's nothing to stop any rate of acceleration in space.
