In particular, an employee of a fire and rescue authority who is
authorised as mentioned in subsection (1) may under that subsection

move or break into a vehicle without the consent of its owner;

That doesn't cut it. What's needed is a law that permits
a) a vehicle to be damaged (eg rammed out the way)
b) no liability for doing it.
Until those are there, almost no firefighter wold want to bankrupt
themselves to save lives by doing this.

The unions would never allow an individual fireman on a call to take the
rap for such a thing. I don't think the public would either. And it'
laughable to think the CPS would consider it appropriate to prosecute
for criminal damage. They'd be more likely to prosecute the vehicle
owner for obstructing the emergency services.
