I've also lived in Spain for a short time, which isn't exactly known for their great drivers. Central Florida is worse by miles. People stare at their phones while moving (at a light is bad enough, but at least you won't hit anyone), they drive with about a car's length of distance while going 45mph, shifting lanes without using their signals and other crazy shenanigans.
I'm just astounded by the complete disregard for other humans while they're in their cars. This is one of the biggest reason me and my wife are looking to resettle elsewhere in a couple of years.
