Pete, bad news - but it sounds like you have been in the right hands and hopefully the detachment will resolve OK with minimal effect on your vision. Look upon the "resting" as an investment in future fun time.
As regards Floaters, these are usually just something we all have to put up with as we grow up. But as Pete says, if you notice a sudden change in position or onset of Floaters and or Shadows in your vision, then get checked out soonest. They are often an announcement of a detachment, which if left untreated for too long can lead to a permanent loss of sight in the affected area of the retina.
Regular eye tests are essential for all of us, even if your eyesight is perfect. Keep it that way and keep on driving.
