I would wager that he's much more likely to be caught driving a Prius at the speed limit in the left lane than a person who hasn't made a comment like that.
These are installed in areas with speed limits at walking speeds. So if you're driving fast enough to damage your car and then seek damages, the best thing will that might happen is that they'll laugh you off. The worst thing is that you'll loose your drivers license. (No tears shed either)
Maybe where you live. In the Seattle area[1], speed bumps are frequently installed on residential streets where the actual limit is 25-30 miles per hour (40-50 kilometers/hour using non-legacy units).
It's typically done in "problems areas" where a small number of people drive 25-50% or more over the limit, but it's extremely frustrating, because it forces drivers to drive way below the actual limit when crossing the speed bumps - especially if they're the bolt-down kind. i.e. the effect is to cause irritation for ~99% of drivers in order to punish a tiny minority.
So if this kind would be installed, then they'd be soft at regulated speed and only solid at speeds significantly exceeding those. I doubt you'd be able to sue the city for breaking your car then - you have been warned. Still, no tear shed.
