In the first clip uploaded by FrankleyMan, he claims that the driver of the ambulance to his right is "yelling at him" because he is not riding on the cycle path, which is on one of the new blue cycle routes in Birmingham.
In the second clip, the cyclist can be heard saying: "It's not compulsory to use the cycle path", after which the driver of the ambulance can be heard saying: "If you'd have got hit on that road, whose fault would it have been?"
The cyclist is correct that it's not compulsory to use the cycle lane, and added that he chose not to use it because he was travelling between 25-30mph. West Midlands Ambulance Service replied:
"Thanks for bringing this to our attention. We will definitely follow this up. Clearly, you don't have to use the cycle path. As for whose fault it would be in an RTC would depend on the circumstances. Sorry about this and thanks again for bringing it to our attention."
They also asked the cyclist to confirm the location and help in identifying the ambulance. Hopefully the driver is offered some serious retraining...
