You cannot drive a car that spooks horses without dismantling it.

The Law

An old motoring law stated that if a driver encounters a team of horses that becomes spooked, they must pull off the road and cover their car with a blanket. If the horses refuse to calm down, the driver is legally required to dismantle the automobile and hide the parts in the nearby bushes. This absurd rule reflects the intense early 20th-century friction between traditional horse-drawn carriages and the first terrifying automobiles.
