It's more to do with the bureaucratic costs of getting a product licensed as a medical device. By the standards of the medical industry, an F1 wheel nut gun or a WEC refuelling rig isn't particularly expensive; the prohibitive part is getting a specialist item approved for medical use. Motorsport can do things that don't scale, because no-one is stopping them from using a one-off prototype made to precisely fit their needs. They (and their suppliers) iterate incredibly rapidly Bringing a new medical device to the market is an immensely expensive multi-year project. Obviously there are benefits to the precautionary principle, but I'm not sure that anyone has quantified the costs.
