In the world of comic book "physics," The Flash (Barry Allen or Wally West) is significantly faster than Ghost Rider. The Flash is the master of the "Speed Force," which allows him to move at speeds far exceeding the speed of light, travel through time, and vibrate through solid matter. While Ghost Rider’s "Hellcycle" is a supernatural vehicle capable of incredible feats—such as driving vertically up buildings, riding on water, and moving at speeds that defy conventional automotive limits—it is generally portrayed as having a "super-human" but not "infinitely fast" speed. Ghost Rider's strength lies in his supernatural endurance and the "Penance Stare," not in pure velocity. However, in certain storylines where Ghost Rider is in his "King of Hell" form or when Johnny Blaze is fully possessed by the Spirit of Vengeance, his speed can increase to match the needs of his mission, potentially reaching speeds that would be invisible to the human eye. But even at his fastest, Ghost Rider cannot match the "Speed Force" feats of The Flash, who has quite literally "outrun death" and "reset the universe." In a straight race across the cosmos, the Scarlet Speedster would cross the finish line before the Spirit of Vengeance had even shifted into second gear.
