Option 1. Honk your horn. Sounds like this is what you're doing, and it makes other people around you more stressed, more frustrated, and less willing to do extra work to help you. After a while, noise like that just gets tuned out.

Option 2. Recognize this is an inappropriate metaphor, and that you are part of an organization that has certain policies and procedures, and that anything being done for reasons other than legal compliance can be up for debate and change.

Do you know why the central IT branch is behind? Are they working with shitty software that makes their jobs harder instead of easier? Are the business processes in place to grant a simple request unnecessarily complex? Is a mistake very costly and difficult to fix, meaning that correctness is incentivized at the expense of throughput? How much is it costing the business while you sit and twiddle your thumbs waiting for approval? Who in your organization has these answers? Who has the power to make decisions about these things? What can you do to get those people together in a room to discuss these issues?

You can get a lot further by trying to fix a problem instead of just complaining about it.
