So many councils are doing this now : you're driving on a 30 road, then it's 20, then there's speed bumps, then 30, then stupid fucking wooden posts stuck in the ground, then 20, then brown tarmac (what does that even mean?), then 30 ... all in the space of two minutes. It's a fucking road. You drive on it. Why so many instructions? I think it's unnecessary and annoying. AIBU?
