The following is why, besides video showing the bleeding obvious, the police are...reluctant to admit it was a chase (pursuit).
This page is from APP, the official source of professional practice for policing.

And from that:
A police driver is deemed to be in pursuit when a driver/motorcyclist indicates by their actions or continuance of their manner of driving/riding that:
- they have no intention of stopping for the police, and
- the police driver believes that the driver of the subject vehicle is aware of the requirement to stop and decides to continue behind the subject vehicle with a view to either reporting its progress or stopping it
When a situation falls within the definition of a pursuit, officers need to decide whether a pursuit is justified, proportionate and conforms to the principle of least intrusion. Pursuits may be spontaneous or part of pre-planned operations.

So straightaway we can see, and know from the evidence, that the first bit in bold is true. Even if not asked to stop, it was obvious they drove towards the police van, saw it, shit themselves, and turned around at speed. This is what instigated the chase (pursuit).

Pursuit prevention
Pursuit activity and use of pursuit tactics are likely to place members of the public and police officers under a significant degree of risk.
Wherever possible, trying to prevent a pursuit from taking place must be a primary consideration.
Officers authorised in pursuit and incident managers must give due regard to the purpose and justification of actions and decisions of a pursuit.
The key consideration is to ask is this pursuit necessary, balanced against threat, risk and harm for which the subject driver is being (or about to be) pursued?
If the decision is made to engage in a pursuit because it is in the public interest to protect life,
prevent or detect crime, or to apprehend an offender,
then it must be conducted with proportionality and due regard for the circumstances. It is important that the risks, topography and continuing surroundings are calculated to justify legitimacy of actions. Officers should not place undue pressure on themselves or risk public safety beyond their capabilities or those of the vehicle they are driving.
To mitigate risk of engaging in, or continuing, a pursuit, officers and pursuit managers must continually ask themselves the following questions.
- What is the nature of the incident or circumstances to which I am now responding or authorising a pursuit response?
- Is a pursuit a proportionate action?
- Do my actions, purpose and objective to stop or prevent further or continuing criminal actions justify the potential risks to life or property?
- Do I have reasonable information or intelligence to indicate that using alternative tactics is preferable to a pursuit?
- Can I plan a different strategy to apprehend the subject driver in the future which is unlikely to compromise evidential requirements?
- Can resources and tactics be used in alternative, preventive ways, to avoid a pursuit taking place?
Before engaging in, or authorising, a pursuit, officers and managers must be familiar with
pursuit considerations.

I'd say this fails on nearly all counts. And, as the officers were obviously totally aware of the area (knowing to go the long way around, therefore knowing about the bollards and fence)
It is important that the risks, topography and continuing surroundings are calculated to justify legitimacy of actions seems very relevant. As does the bit about not compromising evidential requirements.

There's more.
Spontaneous pursuits
These occur when the actions of the suspect driver in deciding to flee
are triggered by the presence of a police vehicle, and there is no prior warning or sufficient time to develop a specific strategy and plans, regardless of whether or not the officer made an initial requirement for the vehicle to stop.
Initial phase
This is the period of a spontaneous pursuit before tactical resolution can be considered and actioned. Pursuit trained standard/response drivers/motorcyclists with suitable vehicles may be authorised to continue by an appropriate member of staff from the control/communications room, but they have no authority to take an active part in tactical resolution. Tyre deflation systems may be used in the initial phase.
Tactical phase
This is the phase of an authorised pursuit, for which appropriate resolution tactics are available. It is commenced by, or taken over by, a tactical phase trained advanced driver in a suitable vehicle, with a pursuit commander identified. Once the pursuit moves into the tactical phase, tactical options for bringing the pursuit to a conclusion will be directed by the pursuit commander.
Authorisation
Officers should seek authorisation for their decision to engage in a pursuit from designated control/communications room staff. The time available between recognising the need for action and the deadline for taking action may be too short to acquire the control/communications room authorisation.
In such cases officers may self-authorise and justify the decision at a later time in line with the NDM. No additional authority is required to move from the initial phase
Pursuit considerations
The following should be taken into account, in accordance with the
national decision model.
- The current level of risk posed by the pursued driver.
- Whether or not the suspect’s identity is known.
- The seriousness of any known offence committed or suspected.
- The weight of intelligence as to whether the suspects are, or are likely to be, armed (see Situational engagement of suspects).
- Whether the driver is, or appears to be, a juvenile or whether it appears that other vulnerable persons are in the vehicle.
- The type of vehicle being pursued, for example, car or motorcycle.
- The current/anticipated route in respect of the time of day, road, weather, traffic, specific considerations such as schools, licensed premises or off-road terrain.
- The availability of tactical options.

Admit it's a chase and you have all that shit (and more, I just got bored of quoting) to cover up.
