Good find!

These bollards are in violation of the government guidelines. Also:

The most effective way of minimising the risk to a pedestrian, a parked vehicle or other obstruction is to have an operator present to initiate the sequence.

If you have someone there anyway, why not have it be a cop directing traffic and writing tickets? Much safer.
