There is no way forward. The road ahead is closed, the way is barred to vehicular traffic. You cannot get through. The barrier is insurmountable and there is a steward stationed there to guard the junction. It is unlikely in the extreme that you would be able to get your car past the barricade.
That isn’t to say that the defences would keep out a marauding attacker, a belligerent invader hell bent on an objective on the other side of the thoroughfare. A brigade of storm-troopers would I’m sure find the obstacle not to be an obstacle, what is actually a piffling plastic moulding to indeed be piffling and no match for a platoon of size thirteen boots stomping forwards with violent aggression, a contemptuous sideways glance the only recognition that there had once been an attempt at a roadblock.
Do not feel that you can treat this as a behavioural role model. The rule of law is there for the benefit of all. It is what makes this country civilised and safe and a thoroughly pleasant place to call home. Be assured that marauders will be kept at bay by the full defensive might of the forces of law and order, themselves no shrinking violets nor pansies blown around in the light prevailing winds of uncertainty.
Stop. The road ahead is closed, until it reopens.
