Noticing the car and driving
Maybe someone has seen this, I haven't read all the posts. But, first the car they are driving has the steering wheel on the right, like the USA. Okay, they might have a rental car and it's American made, but Charlie and his Grandma are from England.
I noticed in one scene, they are driving away and driving on the right, while in the other scenes they are on the left, like they would be in Italy.
I can't think of any explanation for this.
I'm about 3/4 of the way through it. It is a sweet movie and beautiful scenery!
