Opinions on induction after 42 weeks for vbac

I'm UK based and am trying for a vbac. Baby is measuring 3 weeks bigger than he should be and he has a very large head (also 3 weeks bigger than should be).

I have been told that if I don't go onto labour on my own I will be induced after 42 weeks.

I'm looking for people's opinions on the safety of this or if a repeat C-section at 40 weeks would be a better option than going more than two weeks over.

What would you do?
