During the collision between Donald and Lou, Donald's car changes from the usual 1967 Ford Galaxie 500 convertible to a 1968 Ford Galaxie 500 convertible.
During the fender bender the cars change streets. Donald takes a left onto the street with the white house but then collides with Mr. Marie as Donald/Ann are leaving the street with the white house.
The Officer state that Donald was responsible as his turn signal was burnt out. That is incorrect. Whether Donald was turning or going straight, he had the right of way. However he could have been given a ticket for a burnt out lamp.
