You sit on a wooden bench (leather-covered in good buggies). Feet on the floor. Ahead — the horse's back. To the sides — windows (enclosed) or wind (open).
Sounds
Clip-clop on asphalt — rhythmic like a metronome. Spring creak. Wheel whisper. Horse snort. Birds. Wind. No engine, no radio, no AC.
Feeling
Slow. Very slow. After 10 minutes you adjust. After 20 — you realize: you see every tree, every fence, every cow. In a car — blurred spots outside. In a buggy — the world in detail.
