I'm not saying it can be changed in a practical sense. But it a technical sense, by the right person, I guarantee in can be. That right person, might be the person that wrote the code. Or it might be a person that knows how to set it with diagnostic tools.
My VW CC has options like, Rain Sensors that can close all the Windows and Sunroof when it rains. It is disabled in the USA, probably because of liability. But enabled in Europe. I bought the diagnostic tool and enabled it myself (along with a few other things).
I'm not saying it is available through diagnostics but it could be. Could be that the limit is normally 10 seconds, but for liability or laws it's limited to 2 Seconds in USA. But it would make perfect sense to have something like this as a parameter in the system. Could be a recall that they want to change it to 1 Seconds !! And even if it was available you won't find a tech willing to change it. I could not find one to change my auto closing windows, I had buy the tool do it myself if I wanted it.
