Edit: And as I said in the my other comment, if you want people to go slow you need road features that will make them want to go slow on their own. Speed bumps are far more of an insulting road feature than bushes or something to make the road feel narrow because they basically say "this road is capable of X but we're going to make you go Y and you can't do anything about it" which is why people are complaining. If you want people to go slow toss in a raised median and raised curbs to make the road feel narrow.

When I was very young and very dumb, I did ~45 over a railroad track with a raised crossing. I landed OK, but it was a pretty scary experience.

Edit: some people seem to think that I'm against speed bumps to protect pedestrians because of my experience. I'm not really, I was just explaining my experience from when I was an idiot in how these bumps take speed. Sorry for the misunderstanding.

If the driver dies, I put it to you that it was only a matter of time, whether there was a raised crossing in this place or not. This sort of careless driving is vanishingly rarely a one-off, and almost always an example of a pattern of behaviour. Let us hope that they didn't take anybody else with them.

Let me stop you right there. What's generally accepted in the US--not sure about other countries--is to keep your speed less than 10 over the speed limit. This is commonly cited by new and old drivers, driving teachers, and traffic enforcement police. If cars are bottoming out when going over the bump at the speed limit, the road is built wrong.

In Australia you can be fined, heavily, for exceeding the limit by any margin. e.g. Limit was 100kph you were clocked at 102.

If you're driving so much over the limit that you're damaging your car on a properly built speed bump you're going too fast. In the UK you'd run the risk of getting hit with "Driving without due care and attention".

Still, system being what it is, this speed bump makes no sense in the US.
