Physics Tweak v1.61 for ETS2

This mod overhauls the driving physics in Euro Truck Simulator 2 version 1.61, focusing on realism and vehicle behavior. It introduces two tire grip options, simulating how tires perform on dry versus slippery surfaces. This makes tire selection and maintenance significantly more critical, as grip is reduced compared to the default SCS settings. The mod also alters the braking force characteristic curve for a more authentic stop. Expect more noticeable cab rocking during acceleration and braking, with reduced damping that lengthens vibrations. Additionally, the truck's overall weight is increased to 1,200 kg for the cab and driver, with each wheel and tire assembly weighing 127 kg, regardless of chassis weight. Finally, it simulates pneumatic seat suspension, adding subtle camera movement to mimic the driver's view through air-cushioned seats.
