The aircraft shown is a Douglas
DC-4 (round passenger windows). It is identified as a DC-6 (rectangular passenger windows and longer than a DC-4).
The series is suppose to be in 1960. Most of the cars and trucks in the series are from 61-64.
It's a far shorter list to count the vehicles that actually did exist during the stated 1960 year: a 1958 Cadillac and a 1960 Ford. Nearly everything else was built years afterwards. Some examples: a 1962 and 1963 Ford patrol cars, a 1963 Ford Thunderbird and a 1966 Plymouth taxi. There's also the mid-60's Dodge truck (amber turn signals). These mistakes are, unfortunately, symptomatic of a bunch of Gen. Xers and Millennials who simply don't know or care about such anachronisms.
