They say that 50% of drivers are better than average, and 50% are worse than average.
This is meaningless, as 90% of drivers are lousy, dangerous drivers.
There are a lot of cars out there, and therefore you see a lot of driving nonsense. Drivers are texting, reading, and eating cereal from a bowl. Drivers speed into intersections and crosswalks. They crawl at traffic lights, they quickly accelerate and decelerate due to a lack of attention. They ignore signs and roadway markings. They ignorant that the pavement is wet and it's 32° F outside.
In the mean time, the police really can't keep up with it. Pulling people over for minor infractions is a pointless game, particularly because cars pulled over increase traffic and therefore increases the potential for accidents. Furthermore, it isn't right to give someone a $100 ticket for a stupid and meaningless infraction. Cops generally have better things to do.
But when you add it all up, our roads are a dangerous mess. About 35,000 people a year in the US alone are killed on the roadways. But wait! That 35,000 is only counts those that have died, and doesn't bother to count those with lost limbs, brain damage, or a crushed pelvis. In all, over 3 million Americans are non-fatally maimed or injured every year on US roadways.
What can be done? Does anyone care?
