I'd like to have a stab at Blob's - is it THEORISE? (I wouldn't be surprised if it was wrong though.)

Raak copied the buggy v1.0 of my outstanding clue. It's:
Small animal said to be run over by learner driver (6)

Is Rab a learner driver? If so, I wondered if it could be RABBIT (that is, Rab-hit)... just me clutching at straws again, I suppose.

No. It doesn't require anything outside general knowledge - although it could be a rubbish clue. There is a big clue in the amendment. The definition is 'driver'.

Been thinking about this one for ages now - the small animal combined with the learner might suggest the word: GOLFER - GOPHER with 'L' a driver is used in golf, etc etc. I'm having a problem, however, with the phrase 'run over' . If I'm correct perhaps you can explain the last bit of hidden text.
