Lucky or unlucky on Friday the 13th?

I was out for a cycle this morning (Dr's orders) and a motorbike came hurtling past me. I heard the screech of tyres and saw the aftermath a few minutes later as I approached the junction... No sign of the motorbike or rider in the field ahead, so I guess they just learnt a valuable lesson about country roads... Hopefully they just burned a few 1000 miles of rubber from their tyre and did not do any damage to their motorbike.
