Assuming it happened as you said, I don't think you have much reason to be worried. The CCTV footage, presumably, was from a wide angle camera mounted up high on the side of the bus towards the rear. This will support your statement that the bus driver was at fault. The person from the depot which you spoke to sounds to have been unnecessarily aggressive about it, but otherwise it would probably be standard practice to deny fault, despite how obvious it may seem to you.

As an aside, I do remember from my bus driver training, being told that cars are required by law to let a bus out from a bus stop unless doing so could cause an accident. But that doesn't sound like it would be relevant here as you were already beside the bus at the same speed, and the bus wasn't pulling out from a bus stop.

A bit about CCTV footage from the Data Protection Act:

Subject access requests apply equally to CCTV recordings as to any other recorded data.

Individuals therefore have a right to request a copy of their personal data, which includes footage held on a CCTV system, where they are the focus of the footage and/or they are clearly identifiable.

As for your insurance company fighting your corner - add me to the "hell no, they don't" list.

I wouldn't be surprised if this is why there are so many claims companies out there.

My insurer did nothing for a month when someone hit me.

But when a local solicitor took the case on and delivered me a nice hire car with a threat to the other parties solicitors that they would be footing all expenses it was all settled in a week.

Basically I did all their work for them.

You said it yourself, if on average they will win half and lose half then it ceases to be cost-effective to spend time and money apportioning fault when they can just split them all 50/50.

Claims management companies are primarily interested in clear non-fault claims and their interest is not in establishing fault but in maximising claims. In fact your insurer, in the case of a clear none-fault claim, will usually pass it to either its own claims management firm or another that pays them a commission, ultimately paid for by insurance premiums. By stinging each other for inflated hire fees and farming claims for personal injury and loss of earnings, collectively they keep premiums higher than they should be.
