It's the official dress of elegance and Republican centralism, the hue of the office suit and well-tempered culture. Hence does it easily become a kind of drawing-room. Were not the roads in such a bad state, one would believe sometimes that one is on a flying carpet. You can unwind, practice some yoga, take off your shoes and relax your feet. You drive with one hand only, a glass of soda in the other.
Speed being limited, people never get nervous.
Drivers are calm, disciplined and polite. No cutting in front of you the Sicilian way, nor starting like a whirlwind at the green lights. Driving becomes a bourgeois pleasure, it longer tries to outstrip space with speed. It reconciles it with time. You measure your trip in hours rather than in miles.
