> it's banned some places "Engine braking" bans usually target jake braking [0] (opening the exhaust valve at the end of the compression stroke), which greatly increases the effect of engine braking at the cost of producing a very loud noise [1] (which is why it's often banned in residential areas). As far as I'm aware, such bans do not limit the use of "normal" downshifting to decelerate.
