AFAIK DME uses airline supplied flight times based on the flights supplied by guests. Giving a phony flight could backfire if either your phony flight or real flight has a time change that's known a few days in advance.
DME knows how much "wiggle" room the 3 hour pickup time gives them. A 45 minute delay can work with real passengers but might be disastrous for a passenger who supplied a phony pickup time.
Unlike town car drivers DME drivers obey the speed limit.
A person who finagles a 8a pickup for a 9:30a flight should be prepared to miss their flight. 90 minutes is cutting it close, but might be doable, if you're using a car service.
