Don't drive lile a retard and you won't have to worry about hydroplaning...
...pretty damn simple!!!
EDIT: For those of you with plywood splitters:
YOU SUCK!!!! Go make a REAL splitter that won't splinter into a bazillion pieces if you hit it with a fucking pebble... You can make your own carbon fiber or fiberglass one at home, it's not THAT hard. You can make one out of alumalite, which is two thin sheets of aluminum with a honeycomb bonded in-between. Plywood is straight-up backwoods redneck ghetto BS...
