After Hank gets the call from Divya when she is at the airport, you see Hank grab the keys to Divya's car, but when you see him driving, he is in his own convertible.
In the last scene, Hank drives to JFK, but he drives in the oncoming lanes. The white and yellow stripes are reversed; white is always on the right. The signs are on the wrong side of the road and the small one is pointing the wrong way. Also, you can tell that the distance sign is CGI.
