I don't think that Taito game is as impressive. They just don't understand how speed works and their hills are pathetic. The tunnel starts approaching at supersonic speed. But then it slows down for a bit until you are inside the tunnel. Oh, and once you're inside the tunnel the lights on the side are at the wrong place in the distance because the developers don't understand proper perspective, either. They come from above where the ceiling should be to almost down to the car's level. Things on the side of the road move way too fast, likely because they have very few steps of animation.
Road Rash, on the other hand, has stuff all over on the sides of the roads. Not just right next to the edge of the road. The move in proportion to your speed, meaning they don't zip from the horizon to where you are in a single second. Things further away should be moving more slowly and Road Rash does this. The hills in Road Rash are far more impressive and factor into the gameplay (limited viability, etc). All of the sprites have software scaling applied to them instead of being animated in course steps. You can investigate this yourself if you get knocked off your bike and run around slowly. It's just too bad the game has awful colors.
