When I spoke earlier about the customization, it wasn't so much relative to standards, which are vastly different from automotive. I was in automotive before this, as well.
We have our end customers who say that they want ceiling panels that are dove white, and they want bone grey for this and this colour of floor and these seats, whether or not you've ever put them on, and this stanchion. They want a different seating layout and the handbrake to be like this and the driver's dash to be like that. And they want to use this component from this supplier, even if you've never integrated it before, because that sales guy came in and sold them a bill of goods, and they think it will perform for their fleet. Everything is custom, which drives a tremendous amount.... That has nothing to do with specific regulations, necessarily.
I just want to clarify that our heavy pain from customization is not necessarily from the regulatory side.
Maybe you guys want to touch on the regulation side.
