There will be no vehicles driving in front of you after that point (not intentionally anyway).
The ATCO is unable to get in on the R/T to pass a clearance.
Who other than the ATCO knows if the first words are going to be;
Go-arround
or
Cleared to land.
In the absence of the latter, I would do the former as with no ATCO input it is the one which assures safety.
