There's a thin line between genius and insanity, or so says Jeff Schultz who shot and directed this little documentary video called Rampenfest, about a little Bavarian village who built a giant ramp to bring the village closer to heaven ... and to shoot the new BMW Series 1 from Bavaria straight to the United States!

Theoretically it is possible, though not with a regular car, nor probably staying within the earth's atmosphere since you have no additional thrust nor steering capabilities while airborne. In fact, I'd wager you NEED to get outside the atmosphere considering that the wind resistance from a craft traveling the sufficient speed if you're going need to stay within the atmosphere would tear pretty much anything apart. Thusly you'd need a vehicle capable of reentry without burning up, not to mention it needs to be pressurized for the "pilot's" comfort and survival, among other things.
This is definitely one of those things which are better left on the drawing board, or in viral videos.
