It's only a punishment if the bridge falls down. But if someone is making truck drivers drive heavy trucks out onto a bridge to "test" if it will stand up under the load it only seems fair to me that the engineers who designed and built it take the risk alongside them.

I'm positive those trucks are self driven. There is no need for draconian measures you hoped for. Spaceship engineers aren't forced to go into space.

If crossing the bridge you built is as dangerous as going into space, you've clearly done something wrong.
