The French largely gave up on them after 1968 as the cobbles made good
ammunition for the students to throw at the police.


The drivers round these parts just learned that their suspension systems
nicely rejected the frequencies causes by cobbles at 30mph. Of course,
on a non-suspension bike, its a different story.

Our local council tried short patches of cobbles laid more haphazardly
to make them bumpier, instead of speed bumps. The cars were also quite
noisy going over them at speed.
