The way everyone is looking, including the driver, and a rope, I'd say he's towing something.
I'd guess that he's towing just a long rope, in case the "T" stalls before making it all the way across and he needs to be towed back to dry land! "Oh ye of little faith", right?
Actually, in looking closer, I don't think that's a Model T Ford. Maybe that's why the rope, huh?
I think it is already stalled, that is why everybody is there watching?
The front fender doesn't look anything like a T to me, but then, what do I know? Looks like he's being pulled backwards out of the danger.
I would think the car is pulling something/or maybe people from the water to the bridge?? The car whatever it is might be a right hand drive?
Maybe he is pulling a rope across so the people stuck on the other side can get to higher ground safely
If you look closely, the rope is going upstream. I had an old Indian friend that always told me "look closely" The right hand side of the car is downstream.
Hard to tell, but I don't think the rope is going up or down stream. I think it's tied to something taller then the car and whatever is, it's being towed across. Look at what I think is a the low wake at the wheels.
The date says June of 1914 and that is not a 1914 T body - all fenders should be straight without curves. Even the "new" 1915 style wasn't introduced until much later in 1914, and it still should have straight front fenders.
the car looks to me like a 1913 Studebaker mod 35 they had a tool box like that at the back of the car,you can see the door on it.charley
