I certainly can't drive over something which has already been killed! I'd feel awful!!!
I start work at 5.30am so leave the house at 4.50am so I can have a leisurely drive along to work ( it's only about twenty minutes or so ) and am amazed at just how much wildlife there is on the roads at that time of morning. We live two and a half miles into the hills from a main road so I drive VERY slowly ( about 25 mph) along just to avoid the sheer numbers of
Rabbits, wood pigeons, carrion crows, jackdaws and pheasants that seem to regard the tarmac as somewhere to sit in groups!!!
Rabbits are the worst as they will hop away as you approach, almost disappear into the grass verges but then suddenly change their mind and dart across in front of you!!!

Let's just say I've now perfected my emergency stop!!!!!
And on Monday morning I saw two
Roe deer grazing in nearby fields and then, along a straight downhill stretch which is bordered by fields either side and often contains Roe at all times of the day, had THE most enormous Roe buck suddenly charge across the road in front of me!!! I drive a very ancient Micra and I'll swear that deer was bigger than my car LOL He certainly looked like it!
The saddest sights though are the many dead
Badgers and foxes...breaks my heart when I see them and is the reason I prefer to drive at 45-50mph rather than the 'proper' speed limit on these country roads of 60mph.
