English Translation
Tom will be driving through Boston on his way to visit Mary.
As per my review comment, the author on Tatoeba updated the Indonesian sentence:
OLD: Tom akan melewati Boston dalam perjalanan mengunjungi Mary.
NEW: Tom dengan mobilnya akan pergi melewati Boston dalam perjalanan mengunjungi Mary.
Reason: “melewati” means “to pass by” and “mengunjungi” means “to visit”. It can be done by airplane or ship.
