So no one seen or heard of boar RTA's then? if the numbers are as high as some of you suggest I would expect to be seeing as many flat boars as flat roe in these areas, and I doubt that is happening.
You do see casualties from time to time, mainly I see them on the way home in the early hours but a lot of people have slowed down on the roads knowing they run the risk of hitting a pig crossing over the road, I also see a fair amount of cars that have come off the road so not sure if they were involved in trying not to hit a pig. I would suspect that there are numbers of pigs which get bumped but crawl away and die in the woods.
