Some-time ambulance person and crash survivor here[0]. I am delighted to hear of this change, and am also glad to see evidence-based decisions about medical work outside of clinical environments. If you think other drivers drive badly in normal traffic, you should about double that level for the view of traffic from a vehicle using lights and siren. Were it not for patient confidentiality and liability, a channel collecting dashcam footage from fire and EMS vehicles would be both popular and disturbing.
[0] No serious injuries to any of the 5 participants, but a truly massive amount of paperwork.
