I think he is highlighting the small "whistle" devices you can have fitted to the car which is meant to make them nervous and so not come out in front of you on the road.

Something like this - they seem to vary from £3 to £300?

I have often wondered the same thing. Where I come off the A34 there always seems to be a dead grouse and in some cases deer. Having been in a car that hit a deer it is horrible and I never want to repeat it again. As an aside I was told that they also tend to cause neighbourhood dogs to react in various ways. Being able to turn it on/off as you enter/leave town might be helpful.

Everyone loves a Morgan. Even me, unless it's broken again.
