You still need to wash off the dust, so some sort of wipers are needed still.
When swimming, the drag is pretty minor, most of your energy is spent on the displacement of water. That's true with fish, and with ships and boats.

- soperj 12y agoCouldn't you still have sprayers that would help with this?
- scott_karana 12y agoHmm, that's not a bad idea! Current sprayers would obviously be inefficient because they rely on wipers to spread fluid widely over the windshield, but I'm sure that could be changed. (Such as a top pressure-rail for dispensation)
