Amazingly well thought out design. If you want something as impactful (hah) think about the fluid related mechanics of urinal and toilet design, and how much thought has to go into splashback.

Jersey kerb has become ubiquitous worldwide.

Interestingly, the alternate designs often used (guyed wires, steel barrier) have good and bad points, for survivability if an impact is unavoidable. They "give" -and in some circumstances, thats exactly what you want. Jersey Kerb is for the "nope: no giving here: wear the decelleration, hard" situations where giving (eg. into the oncoming traffic flow) would be worse overall.

> splashback

I thought that is what the plastic filters at the bottom assisted with

They do, but well designed urinals have very little splash back even without the plastic filter.
