> With the road metaphor, one issue I've seen is ops will create a rope bridge and get mad when devs need to drive a car over it. "You shouldn't do that! You idiot! Just walk over the bridge like we expect!"

Well, the main problem with the "bridge mismatch" is usually that resources required for an environment are not free. Its usually the opposite, most infrastructure is rather expensive, and running multiple systems side by side because multiple developers require slightly different versions of the same thing tends to explode cost.
