Is it permissible to visit others while there is a clear scent of incense, knowing that the scent is unintentional and postponing the visit may cause embarrassment or anger to the one giving the ride?

Congratulations on your eagerness to avoid what displeases Allah. Continuing the visit after applying perfume has a few scenarios: First: It is forbidden and a major sin if it leads to fitna (temptation/strife) for men. Second: It is forbidden but not a major sin if fitna is highly probable. Third: It is makruh (disliked) if it is highly probable that fitna will not occur, yet there remains a fear of it happening.
