A (Crazy?) Suggestion

[Tommer]

I had an idea just now and I don't know how other people will view it or to what extent it is possible..

Put simply, my suggestion is a creation for automatically changing sirens, EG From 5 to 4 on approach to junctions..

The idea would use some local insim to determine your location relative to junctions and on approach maybe the tones will switch over and then back again when you leave the junction?

I know it sounds a little far fetched at first but I thought I would put the idea out there since it is probably achievable.
