Magic constant

[adbor]

Hello enginBozkurt

Thank you for this project. It helps me a lot to understand main principles of Car Control. Everything in your code is clear, except one thing
in this file https://github.com/enginBozkurt/SelfDrivingCarsControlDesign/blob/master/PythonClient/Course1FinalProject/controller2d.py

self._conv_rad_to_steer = 180.0 / 70.0 / np.pi

What 70.0 means? Why we need to scale
input_steer = self._conv_rad_to_steer * input_steer_in_rad

Thank you
