I think a lot of players probably made the same mistake I did. When you see a bright red warning message saying "SLOW DOWN", you tend to hit the brakes! And when you do, the message disappears... which reinforces the assumption that you were going too fast, for some reason. Also if you DO go too fast, and end up zooming past a planet and having to do the "loop of shame", you probably did notice the "SLOW DOWN" message as you shot past.
It wasn't until I came on here that I discovered that it was a warning that I was experiencing a gravitational slowdown effect: passing through a gravity well slows your top speed, and if your current speed exceeds the new top speed, you get slowed down and the warning appears. You don't have to slow down, just leave the throttle alone and keep going! (...and maybe try to swing out around intervening planets if you spot them).
It could be a little clearer if that space is removed: you don't need to SLOW DOWN, you are experiencing a SLOWDOWN. And surely this would be a very trivial fix!
