Even from the standpoint of an automotive distributor supporting our dealer network, obviously those technologies change all the time, and we have to regularly retrain our personnel to be able to support those vehicles. That said, one of the things that is happening is that, given the rise of electronics in vehicles, many of the systems are actually easier to check with various available tools.
As the nature of those systems and the technical challenges change, so too does the standard knowledge, and some of the old issues tend to go away. For example, I think the last time I was here I mentioned that in the past one of the things that was common across the auto industry was to experience binding of throttle cables. Because those cables don't exist anymore, that's an issue that has gone away as we've moved to new technology.
I think everyone in the industry is learning and changing their skill sets and the tools that we use to look at it. I've heard the department say they're of the view that they have the resources necessary for the job. Clearly, if the job changes, that's a separate question.
