The Casalini Sulky, an early three-wheeled microcar produced by the world's oldest microcar company, Casalini, is notorious for its extremely precarious driving experience. With an engine often less than 50 cc, driving the Sulky means feeling the instability, especially when braking, as the vehicle "slightly decomposes to the right." One driver noted that every pothole felt "as if you were approaching death" and that the vehicle is "ready to flip over immediately."
