This is quite a confusing but interesting topic, I'll admit I am not entirely informed on the intricate details of relativity, but I believe I have a good grasp of most of the general effects. See >picrel, the car thing is not accelerating at all, it is at a constant velocity moving in a straight line on this deformed space. If you take this into three dimensions with relativity, then the exact same thing is happening to satellites. They are not accelerating (which is why astronauts experience zero-g), they are moving at a constant velocity in a straight line through space time. I believe a lot of the confusion comes with the most common explanation of how gravity works with relativity, the sheet with a heavy mass warping space time. This thought experiment doesn't really explain geodesics at all.
