and I never seen the sod of turf until it's way too late

The story:

I had my "candygram for mongo" moment when after years of listening and singing along in the car to the song I read the lyrics in the cd cover and realised my mistake. Doh!!
In my defense though my line makes sense because in the song the bike skids off the road which could happen if you hit a sod of turf on a corner going really fast.
