Why oh why oh why do they insist on putting them in the middle of bends? Does anyone at the council know what they do to bikers!?

On the way to my new house I counted 12 manhole covers in places where they can cause me to lose grip as I’m going around a corner…12… and not those nice studded ones… the ones that cause you to slip, even in the dry… I guess it’s time I bought those engine bars.
