The sign says "'Gate in Use 24 Hrs keep clear"
Assuming "hrs" means hours, this could be taken to mean "this gate is used by through vehicles at any time of day, so you must not park here". Which clearly the Astra S199MTR has done. So it must mean something else. Such as "This gate is in use as a parking space for S199MTR, all other vehicles must not park here". That makes sense.
