Does adding dimples to a car?
The theory or the improvement is that, like a golf ball, the dimples would reduce the car's drag through the air, thus allowing it to travel the same distance at the same speed using less fuel. So, in a difficult economy with high fuel prices, a dimpled car design can very well save you some cash.
Can a golf ball break a car window?
So while a baseball or golf ball may have a huge impact on the vehicle, the ball will not actually break through the windshield. Other parts of the car, like a sunroof or a rear window, may not include the laminate but instead have tempered glass.
Why do cars not have dimples in golf balls?
The dimples in a golf ball promote an earlier transition to turbulent flow and thus reduce the pressure drag of the golf ball, so it can fly further. In a car, the size is large enough to develop a turbulent boundary layer early on. Dimples would not help, but increase drag slightly.
Does adding dimples to a car increase gas mileage?
Yes. Apparently, covering your car in clay and dimpling it like a golf ball will result in a significant increase in gas mileage.
Who is liable if a golf ball hits a car?

Why do golf balls have 336 dimples?
Essentially, golfers would have little hope controlling a smooth golf ball. When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight.

Do dimples increase aerodynamics?
First, dimples allow air to flow more smoothly around a ball's surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.
Do golf ball dimples reduce drag?
Golf ball dimples reduce drag by creating a turbulent boundary layer flow around the ball. The boundary layer is defined as a thin layer of fluid dragged by the ball. By creating this turbulent boundary layer, the separation point decreases.
Do clean cars get better gas mileage?
While it might seem weird that a clean car can achieve better fuel economy, it's not. In fact, it really comes down to aerodynamics. The protruding dirt and debris on your car create a rougher surface for the outside air to flow around.

Why don't cars have dimples?
The reason the dimples reduce drag on a golf ball is because they trip the boundary layer in the region where the flow separates, and that causes the wake to be smaller and have less pressure drag.
Do wings get dimples?
This same effect does not work with streamlined bodies and that’s why wings do not get dimples. A car is partly streamlined and partly a bluff body. But the Reynolds number for a car is way too high for this quirky effect to be relevant.
