toward or towards depends on plurality of context....

your car is headed towards the finish line

Couch/sofa
It's a Pepsi (that's what I drink), generically--it's a soda
Toward

Chair

Soda( soft drink sometimes about equal with refresicas)

Depends on context

couch

tords

Couch, Soda, Torsades

Couch

Pop

Depends on context

(But NEVER add an S to anyway. Just don't.)

To me, it's not the plurality of the subject, but whether there is movement. So I'd agree with both your example sentences: because toward means a certain direction while towards means actually moving in that direction. (To me, anyway--I'm not saying there's a grammatical rule about that...)

couch

pop

two swords.

you may be onto something there. I noticed when i was making the example sentences that headed sounded better in the second one....

what would you say if my plane was on a treadmill flying in the direction of the finish line, but not actually moving because of the treadmill?
