The examiners don't judge that. They just check that you meet the educational requirements, that you did an apprenticeship under supervisors who have a good safety record, and that those supervisors think you are qualified. Then you get your license. If there's a safety incident relating to your work and you were acting recklessly, you may lose your license.

That's the whole process. Repeat that over a long enough period of time and you tend to select for a more competent, safety-conscious group of engineers.

Over the long term, its survival of the fittest. Reckless engineers have safety incidents and get barred from both working and from supervising new engineers. So, it tends to be the safer engineers who get to pass on their work culture to the next generation of engineers.
