There I was, just enjoying the moment.

Well, not really.

I pulled out of this side road and onto the main road and off I went. I soon caught up with this ambulance in a 40mph zone and he was doing around 33mph.

I was in no rush, so I just kept a nice distance between us. And then it happened! Did I see it first, or did the ambulance driver see it? He applied his brakes - slowly at first - then swerved onto the other side of the road into oncoming drivers who nearly mounted the kerb.

I thought what a t-----t, what this man had just done was so stupid and what did he try to avoid? A squirrel running across the road.

Yes I know, why run something over if you can avoid it? But to put others in danger well, you can imagine what I shouted at him through the cab window as we sat at traffic lights.
