That's not exactly an apples to apples comparison the space shuttle's record sit's between cars and commercial aircraft in deaths per passenger mile. 14 deaths in 20k orbits * 7 people @ 42k miles per orbit. = 1 death per 420 million miles vs commercial aircraft which sit at 1 death per 2,000 million miles vs cars at 1 death per 80 million miles. But, the shuttle is not exactly a safe ride.
Now, if you line things up by trip, it's car's then aircraft then the shuttle.
