I really like how Toyota made subtle changes to the regular Prius badges without going overboard. Just figured out while cleaning the car that they also modified the HSD badge on the trunk: Just a random 'kudos' instead of a complaint thread
I feel better now. When I got my first Prius, I washed it one weekend and when I got to the back, I took a good look at the emblem and realized the notch on the top and bottom made it look like an H. As soon as I saw that, I then saw the S and D.
