EMS in the UK is charity funded and therefore the commercial pressures are not there. Although it's a small country the accident rate is almost non existent.
True, but the pressure to keep the charity money coming in causes other problems, such as unrealistic desire to attend every possible incident, even in difficult terrain, and then extreme reluctance to admit defeat and let a more suitable asset (eg a SAR helicopter) take over. This attitude doesn't result in crashes but it does mean that a lot of casualties experience a great deal of unnecessary discomfort and delay in getting to a hospital!
