I've had a quick Google for disrupting ambulances, because that's come up a couple of times on the thread. XR say:
What is your policy on emergency vehicles?
We have no intention of delaying emergency vehicles and are working with the police to make sure this doesn’t happen.
Giving notice to the police allows plans to be put in place to reroute vehicles.
What if an ambulance doesn’t get to the hospital in time because it is delayed by you, and someone dies?
When there are traffic jams, ambulances are redirected by their HQs. If the ambulance is already very close to the roadblock, it is let through by the protesters. We usually advise of disruption before it happens, there are frequent traffic jams in London due to all manner of things such as road works and accidents and the services have strategies for coping with them, we aim to give them the necessary advance warning so they can alert crews and re route on the day.

Despite some pretty scathing articles in The Telegraph and The Mail, the worst disruption of emergency services anyone seems to be able to find is a non blue-lighted ambulance who got stuck in the queue. All blue-lighted emergency vehicles have been let through. There's a quote from Bristol Ambulance Service about the summer uprising here:
"We have been working closely with Avon and Somerset police, health care partners and other key organisations, in monitoring the situation very closely all week, to ensure that the delivery of patient care has not been adversely affected by the protests.
"Through this partnership working we have been able to keep our staff fully updated on any disruption, including road closures and mobile protests around Bristol City and normal trust services have been maintained for the community.”

I think it's pretty telling that the worst crime the PP could find was a man who missed his father's death bed. If XR really were blocking ambulances and interfering with emergency services don't you think she'd have found something that impacted on a blue-lighted vehicle? Somewhere? Anywhere?
Speaking personally, I've not been to the protests in London, but I did take part in the climate strike and it had quite the opposite effect to the one you suggest. I came away fired up to do more. There are even more protestors at this one than the last, and they show no signs of letting up the pressure.
The crusties comment made me laugh. Half of this thread is insisting the protestors drive 4 by 4s and love shopping. While the prime minister is insisting they're all hemp-wearing hippie vegans. Which is it? It can't be both.
