I think by this point, Mycroft has probably ceased to think clearly ;-). After all, he has cleverly:
* persuaded sexy inspector into his car alone
* correctly deduced that sexy inspector is bisexual
* found a semi-plausible excuse for asking sexy inspector to take his shirt off
He has also probably spent substantial parts of the afternoon fantasising about Greg, in between getting Sherlock to solve his case for him, so he may be even more off balance. But I see Mycroft as making a mistake that both he and Sherlock are sometimes prone to, of coming up with such ingenious short-term plans that they forget about the long-term problems/consequences (Bond Air, solving Irene's e-mail message etc).
And I also wonder whether Mycroft subconsciously thinks that he is so far away from home territory (Croydon!) that it somehow doesn't count and no-one will ever find out about it.
