Re:the white Hyundai Elantra. As I mentioned before, they are looking for a 2011 -2013 when that generation of that vehicle ran through 2015. This mean whatever or WHOEVER saw it could identify that the wheels were different, front fog lights were different, the grille is different, the back reflectors were different, all or was able to identify one of the interior features as being specific to 2012-2013 only.
Side view could get the wheels and the front fog lights. To see the back reflectors you'd pretty much have to be staring at where the license plate would be. Grill you'd need a side front diagonal minimum.
Someone could have seen the vehicle coming towards them as they were going some where, either on foot or in a vehicle (some of the drivers who get people home safely were likely still out). The vehicle might have been seen on camera footage they aren't releasing. It might have taken this long to get the car they are interested in pinned down to a 2011-2013 because of the differences. No use looking for a two door when the 2021-2013 didn't have a two door.
I do wish LE would be more specific, highlight what is special about the 2011-2013. Must be 4 door. Rear reflectors are angled under the bumper. Wheels look like this (image of wheels). Fog lights are this shape (image of that). The Hyundai logo looks like this (image of logo). That way they wouldn't get tips on 2014, 2015, Hondas, or wrong wheeled vehicles.
Most people wouldn't know what year a car is, but they can tell a black grille from a chrome one.
