Road is wet why might a motorcyclist steer round drain coverd on bend?

A motorcyclist may steer around a drain cover on a bend because wet surfaces can be particularly slippery, and drain covers often have less grip than the surrounding road. Navigating over a wet drain cover can lead to loss of traction, increasing the risk of a skid or crash. By avoiding the cover, the rider can maintain better control and stability while cornering. Additionally, drain covers can have a different texture or be slightly raised, further complicating the handling of the motorcycle.
