If Michael Bay Remade TAXI DRIVER ...

... it would star Shia LeBeouf as Travis Bickle.

Take place during extremely sunny daylight.

Have a scene where his taxi is pursued by a helicopter silhouetted against a setting sun.

His taxi would have the capability of transforming into a friendly robot who helps him fight crime.

Shia would cry.

Have a scene wherein Travis looks incredulous when the taxi/robot speaks to him for the first time and he replies,
"Ar-are you ... talking ... to ... ME!!??"
