Do you still think slowing in gear uses more fuel then coasting in "neutral"?

Your stated safety concerns do not apply in the situations where I would consider coasting. Therefore your experiment is entirely irrelevant! An equivalent would be a blanket statement (not by me) that driving with the lights off is dangerous. I would counter that in some situations, driving with the lights turned off (eg daylight!) is absolutely fine - to which you would reply "Just you try driving with the lights off in the dark and see how well it goes". Would you be surprised if I declined to try it?
And yes, I suspect that slowing in gear uses (slightly) more fuel than coasting in neutral, because in the former case the engine is turning at higher revs, and therefore needs more fuel to stay running than an idling engine. But I'm happy to be proved wrong!
