Absolutely. It should be very rare occurrence and due to multiple errors on the drivers part. TFL's claim that this road is potentially used by many high vehicles is potentially nonsense. And remember of those few, it is only the long/wide vehicles that might have trouble negotiating an island.

That pedestrians have trouble crossing Waldram Place many times a day - at both ends - is a fact.

As for sending a similar lorry down Devonshire Rd, a road that white vans often have trouble negotiating - they would have no chance!
