Mexico can be tricky to work out, since the plates are so varied and the country has deserts in the north and jungles in the south. The sometimes-visible stubby antenna on the camera car is not unique to Mexico in Latin America. Mexican stop signs say ALTO, which is also true in Guatemala, but the camera cars are very different, with Mexico's having no bars or visible side mirrors. Mexico also has recognisable octagonal street poles. If you see pink taxis, you're in Mexico City.
Plates
Mexico has a wide variety of plates, which are issued by district. The dimensions are largely consistent; Americas-style narrow and tall. All districts use white backgrounds, but some have black text, some have blue text, and some have background graphics or horizontal strips which can affect the tint of the blur.
Road markings
White outer lines and yellow inner lines. Often in Mexico you'll see a single, solid yellow center line, which is uncommon elsewhere.
Road signs
Mexico and Guatemala use ALTO stop signs (as opposed to PARE in the rest of Latin America). This can be very useful in identifying Mexico because Guatemala's car is very distinctive.
