No, but that's why we're not talking about a sign, but a raised crosswalk (i.e. a speedbump.) If you're going over 35mph, your car will scrape against it and possibly catch air off it, and you'll quite quickly regret going over 35mph and probably not do it again on that stretch of road.

Or you might be dead or your car might be wrecked.

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 car is wrecked, this will definitely discourage the driver from doing it again.

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.

It was a one off for me! When you are 15 years old with a drivers license, you are learning lots of things for the first and last time. For example, I quickly learned about hydroplaning during a heavy rain storm.

Far more pedestrians are hurt and killed by vehicles than drivers are hurt by speed bumps. As someone who both drives and walks, I believe it is 100% acceptable to trash a few people’s cars (who ignored the speed limit) to reduce pedestrian fatalities.

Please don't assume I think this is a bad idea. I was just explaining the consequences of speeding over a bump like that, I'm completely pro speed bump as a way of slowing down traffic. Just that we can be idiots when we are kids.

Better a careless driver dead than an innocent pedestrian on a designated crossing.

This was a road in the country out in the middle of nowhere. There were no pedestrians, and the RR crossing was only protected by this bump and some lights (no gates).

No, if the majority of drivers want to drive faster than 35mph, the road is badly designed. It needs traffic calming devices, such as narrower lanes, curb extensions, and, yes, raised crosswalks. Enforcement (including automated enforcement) is a useful tool, but the start should be designing the road so that drivers naturally go at a safe speed.

Yeah, that's what traffic calming measures such as raised crosswalks are for...
