I do comprehend the delicate nature of the test equipment. I would also not hesitate to ask to borrow your expensive racing car for a test spin around the track. Sometimes people who have access to these things are willing to share them, especially right before routine maintenance where the tire, engine, and motor oil will all be tossed out and replaced. For a racing car this may happen after each race, for the testing equipment its not as often but when it comes time for the procedure sometimes it can’t cause problems because the business end will be replaced in the process.
Again, not likely to happen but it will not happen unless you ask.
I have built access roads into National Parks for emergency response purposes, it would not have happened unless I had asked. Lots of people were surprised that I got permission, many separate instances and purposes, asking is the key
