Vital fluids, the lifeblood of any engine, slippery… maybe even deadly when wet and laying on the road beneath your contact patches. What to do? When you see glistening areas ahead, steer to a non-shiny portion of the lane before reaching the shiny stuff. If caught by surprise, try to coast through it in a straight line. If the road and/or traffic eliminate the coast/do-nothing option, then try to slow-down as gently as you can, avoid firm/sudden control inputs, balance front/rear brake applications and ease-into those levers instead of grabbing them in a panic. With a little luck, even surprise patches of snow and ice (don’t ask!) can be negotiated provided a rider is smooth and careful with their control inputs and has enough road to allow them to coast through in a straightish line.
