It's extremely rare for bridges to fail. I certainly wouldn't expect a bridge to fail given modern safety standards.

You might have marginally more confidence in the bridge after a few hundred thousand cars, but we have processes in place to be confident within reasonable doubt that things are safe before that.

No one is claiming that anything is "100% safe". That's an unachievable level of confidence. If everyone waited for a hundred thousand other people to do anything we'd never get anywhere.
