British bollards on the other hqnd tend to be stout and solid, after the Battle of Trafalgar it was found the French guns that were captured could not be retrofitted into British ships so they got turned into London bollards as a way of rubbing it in. While only a few of these still exist, they inspired the general shape of London bollards for a long time.

Also can't believe I can remember bollard lore but not important things

And then drivers would learn to slow the fuck down. Problem solved
