Mobility is changing - whether we choose to notice it or not. Rising energy volatility, increasing costs, and growing regulatory pressure are reshaping the foundations of personal transport. The combustion engine, once synonymous with independence, is becoming part of a system that is harder to predict and harder to control. Electric mobility offers a different structure. This book provides a clear, practical analysis of: real costs over time, infrastructure and everyday usability, environmental impact beyond simple assumptions, and the strategic question of when to act. It is not a technical manual. It is a decision framework. For anyone asking not if, but when to adapt, the answer may be closer than expected.
