consistency? no thanks i'm happy riding in counties that let loud cans go:confused

(b) power to seize and remove the motor vehicle;
(c) power, for the purposes of exercising a power falling within paragraph (a) or (b), to enter any premises on which he has reasonable grounds for believing the motor vehicle to be;
(d) power to use reasonable force, if necessary, in the exercise of any power conferred by any of paragraphs to (a) to (c).
(4) A constable shall not seize a motor vehicle in the exercise of the powers conferred on him by this section unless-
(a) he has warned the person appearing to him to be the person whose use falls within subsection (1) that he will seize it, if that use continues or is repeated; and
(b) it appears to him that the use has continued or been repeated after the the warning.
(5) Subsection (4) does not require a warning to be given by a constable on any occasion on which he would otherwise have the power to seize a motor vehicle under this section if-
(a) the circumstances make it impracticable for him to give the warning;
(b) the constable has already on that occasion given a warning under that subsection in respect of any use of that motor vehicle or of another motor vehicle by that person or any other person;
(c) the constable has reasonable grounds for believing that such a warning has been given on that occasion otherwise than by him; or
(d) the constable has reasonable grounds for believing that the person whose use of that motor vehicle on that occasion would justify the seizure is a person to whom a warning under that subsection has been given (whether or not by that constable or in respect the same vehicle or the same or a similar use) on a previous occasion in the previous twelve months.
(6) A person who fails to comply with an order under subsection (3)(a) is guilty of an offence and shall be liable, on summary conviction, to a fine not exceeding level 3 on the standard scale.
