Yeah but it depends on how you define dangerous. I only heard of this clause being invoked once and it was not to do with the car but the tester, your man was being a pr*ck and was just having a bad day and failed someone for an item on a retest that they had originally passed ( think it was a reg plate that was hard to read). When the customer objected, your man the tester quoted the clause that allowed him to fail the car for this even though it had originallly passed. When he was asked how reg plates inmpacted public safety, he said if the car was involved in an incident, it would create difficulties tracing the car or reporting the incident as the car would be harder to identify.
This is very much a worst case scenario. You'd be very unlucky to be failed for the windscreen after passing it the first time. In any event, they can't just fail the windscreen because there is a crack in it, it has to be within a certain visual "zone" on the windscreen and be a predetermined length. Unless the window is smashed or seriously damaged and obviously creating a problem for driver visability, I wouldn't worry about it...
