Overtaking down the middle is the accepted custom and practice along here and it's a VERY fast and busy road (Here is an example). You either have to go with the flow and join the overtakers, or sit tight and be overtaken. Opportunities for "normal" overtakes are few and far between.

Now, however, it's simple a two lane carriageway, with extremely wide lanes. 3 cars can fit alongside comfortably, though I'd not like to try 4 (especially if one is a lorry).

TSM is guidance not law. No such regulation exists.

Apologies for the inaccuracy - I was trying to put a number on the minimum width of a 'normal' UK single carriageway which has a centre line and lanes of opposing traffic, for the benefit of our friend from Israel (who still has an unread PM from two weeks ago).
If cars are approximately 2m wide, and a single carriageway is, in general, at least 5.5m wide, there is only room for one car in each direction plus a margin for safe passage.
