i ran over one earlier and somethine clanked on my car, i hate and loathe them, they ruin cars and no i do not speed over them but just the normal driving over them ten times a day ruins springs and other parts costing loads of money.
I would prefer a speed camera, in fact speed cameras up the whole of the roads with bumps. i do not speed in my car but the bumps are starting to really irk me now.
i expect people will say iabu but i don't think i am, i just think there are other and better ways to slow vehicles. chicanes to slow flow etc. placing massive humps in the middle of the road isn't the way we should be heading [grr]
