The other car then slows down until it is just feet in front of you, forcing you to make a quick decision to slow down, change lanes or even swerve off the road to the right to avoid a collision. Now imagine the same scenario involving two satellites orbiting 22,000 miles above the earth and traveling at 6,800 miles per hour.
