Speed Hump Evolution

The usual cycling route have had a road construction recently. When I tried going on the road today, it was already done and I witnessed something extraordinary.
The speed humps have evolved.
It used to have horrible weird coloured ugly ones but new ones are like spaceships. The new generation is far much lower, smaller and cooler.
The amazing thing is that, although the same materials are basically used, an evolution happened. This means humans’ perception has purely developed. I like this way of technological development, probably drivers now noticed they can go slower without that much gap. Everyone became more sensible… I hope…
