Scouser you are right, it’s the central reservation between the two opposite lanes. Mostly its made of concrete.
its a bit hard not to wear the gear all the time. However, after wearing the protection, and especially after the crash, I fell naked if I am not wearing my jacket and helmet. Helmet is a must, and I wear it even if I have to go just half a block away. ( Helmets are not mandatory in most of the places here!)
