Here in the USA, we have speed bumps too. This is why we need to buy huge SUVs with high clearance. With a big enough vehicle, the speed bumps are not an issue. You should try it.
I often wonder what the environmental cost of speed bumps is. It is normal to drive huge SUVs. It is normal to slam on the brakes, go over the speed bump, and then hit the gas. There is also an environmental cost for broken parts that need to be replaced and oil that leaks from broken oil pans.
I bet if you combined speed bumps with a decent gas tax (with tax discounts for business use) and eliminated the "light truck" tax loophole for SUVs [1], you'd probably wipe out the huge SUV syndrome.
Of course, SUVs are highly profitable for the auto and petroleum industries, heavily represented in lobbyist circles, so it's pretty much a no-go.
