Would you allow a passenger to 'have a go' on the controls?

So on that argument, is the autopilot included in the insurance policy?

If you call it George then maybe you need to add it.

I do not see that it is an issue.

It's not whether you think it is an issue - it whether your insurers do. In the case cited they thought it to be an issue and voided the policy.
