Re: Obvious solution
The real problem with hitting a roo isn't the damage the impact does to your car - though that can be substantial - it's what else you hit afterwards. People take wild evasive action and hit something, such as a tree or another car. The impact of a roo is substantial. It can do a lot of damage, including damage that in some cases makes it difficult or impossible to control the car well enough to bring it to a safe stop.
I regularly drive through a particular section of road arund dusk. This is the worst possible time for roo stikes. I don't worry too much about hitting a roo myself - I slow down to 80k or less and keep a very sharp lookout - I worry about the moron coming the other way at 120 who suddenly sees a roo (or just feels the impact on an unseen one) and unexpectedly arrives on my side of the road, out of control. It hasn't happened yet 'coz I'm here to talk about it, but honestly, some people have got no bloody idea.
