Physics from Automobile

Automobile is the best example to explain physical system. Why?

1. Mechanics / Dynamics
F=ma (Newton's law) : Acceleration system
Friction law : Brake system
Rotation dynamics : Tire, curve driving, rain wiper ...
Momentum / Energy conservation : Collision simulation and car accident

2. Electromagnetism
Maxwell's law : Radio antenna
Ohm's law / Kirchhoff's law : Battery electronics, Fuse system, ...
Faraday's cage : Car body is safe from lightning.

3. Thermodynamics / Statistic physics
Carnot engine : 4-cycle engine

4. Wave mechanics
Sonology : car audio system
Noise reduction from outside

5. Optics
Lense system : head light, rear light (Parabolic mirror)

Of course, there are so many technical features that I don't mention above and I don't know.
Some people ask for what is physics useful. This is an answer.
