Actually, once I'd insert them fully, I didn't notice I had them in at all… unless I was driving round lots of corners… or judder bars… oh my, the judder bars!
The Government plans to install judder bars or traffic islands on the main road around Rarotonga in an effort to curb speeding drivers.
Anyway just take it easy around Innes Common as it's only 40 (this speed limit is ridiculous, and as for those judder bars now!)
There were none of the modern judder bars to slow traffic, but the corrugations in unsealed roads especially on hills and on corners could have the same effect.
