From what I can tell that Audi was impacted by the Mog on its passenger side. Probably the Audi got onto the road without proper space for the Morgan to slow down.
You really have to become the world's safest driver in those. I can believe Alex Roy daily drives it in NYC and crossed country in one.
I agree, that looks the most likely scenario. Maybe the Audi driver just didn't see a bright orange 3 wheeler coming towards him and just pulled out in front of it?
I wish the driver and passenger a very speedy recovery with no lasting effects. It's awful to see the aftermath of something like this.
