No they won't. If the map says they won't fit. They won't drive there.

How many times have we seen someone drive the wrong way down a one way street, drive down an alley too narrow for a car, drive over a pedestrian bridge, etc because their GPS navigator told them to? A self driving vehicle is only as good as the programming it contains, we are a long way off from being able to put in a random address and have the car take you there reliably.

FYI, it seems to be about one such crash per month. Very few injuries, no deaths AFAIK. It’s not this hellish deathtrap you seem to have twisted it into in your mind! (Heck, I think the real worry was about damage to the railroad bridge, since any damage to the tracks could cause a derailment, which could wreak havoc and cause true death and mayhem.)

Nobody's biting because the question forces people to think of the problem in more nuanced term than just black and white. People don't like that and I completely understand. Of course it's more satisfying to feel superior and shake a fist at others. Nuance is tiresome and requires taking a look at your own mistakes too. If you look at the avalanche of self-righteous replies here, we must have a crowd that's surprisingly adept at driving cars safely. That coincides with up to 93% of drivers thinking they are above average in regards to safety, but is obviously unlikely to coincide with the actual numbers.

You indicate correctly why it might actually be a rather dangerous problem. There's plenty of examples around where bridges got damaged to the point that crossing wasn't safe any more, or even serious accidents happening. A truck veering into the wrong lane and into another car isn't unimaginable either. History is full waiting for deaths to finally act.

To me it's a clear cut UX problem, which is why your stance on the matter honestly surprises me a bit. There is an obvious mismatch between the desired behaviour of people and the actual behaviour. The behaviour is consistent too. If you design a product and people electrocute themselves with it every month, I don't think the authorities would take very long to act. It might not even make it to market, as preventing people from hurting themselves is getting ever more attention.

What happens then is that people fail to notice the roundabout and drive right over it.

On one memorable occasion two people drove over the top of a local roundabout from different directions at the same time and collided in the middle of it. The newspaper photo of the two wrecked cars perched on top of the roundabout was a truly WTF moment.

And I've seen one with a sign says "no left turn". It's as stupid as putting a sign on your car says "I stop at stop sign" or "I stop at no turn on right", and I've seen both. Seriously.

Not so stupid when you realize how rare roundabouts are in the US. So there's always someone coming along who's never seen one before. Redundant signage is essential!

I think some here mentioned options are more expensive than just digging the road a little deeper like the water curtains, those are probably very expensive and do only get used when the tunnel is built and not 10m long but 100m.
My idea would be to completely limit passthrough for trucks altogether even for smaller once so that wouldn't be any more a problem. Another solution might be the steel pipe option like mentioned earlier its a very cheap and effective option gets used in Europe (Italy) a lot for tunnels and bridges.
As soon as you start aiming for electronic solutions you may start digging because most electronic solutions will be more expensive than just a sign limiting passthrough or lowering the road.
metrologist:
Arduino connected to a Lazer sensor to detect truck height. The Arduino gets the lazer signal broken and activates a conveyor on the road to stop the truck collision. It's new Smart Bridge technology.

Or the waterfall stop sign was good too...
