He would probably be OK off-leash,

I see nothing in your post that would lead to this conclusion.
The fact that he didn't go into the road or take off into the woods *this*
time is no guarantee that he won't next time.

I just can't take that chance. We were probably very lucky on this
adventure.

I don't think there's any "probably" about it, given the speed people hit
on Warren Road, and the fact that he still has no recall.

I already know that I should have had him on a harness, rather than a
choker chain in non-choke mode.

Why a harness?
For tethering while you're out with him, IMO your best bet would be a
martingale aka "combo" collar; Petsmart sells them cheaply, and the shop
next to Falls Road Animal hospital carries (or used to carry) Lupines, which
aren't cheap but last forever (and have a lifetime guarantee, to boot).
Most professional or commercial dog walkers insist on them for client dogs,
because if they're adjusted properly, they're damn near escape-proof but
can't choke the dog, and are comfortable otherwise. Not to mention easy to
take on and off, since they just slip over the dog's head.
