No insurance since it was a relatively cheap push bike... So... No engine.
Hopefully, my college travel grant will have come through... i'll pinch a bit out of that
Err - as Chegs kind of says - bollocks to that.
The dozy fucker hit you with a car, you are entitled to compensation for the sheer fact that they hit you. See a solicitor on legal aid, not an injury lawyer for you, or sign up to the CTC and get free representation that way.
You are entitled to claim from them for their rank stupidity and by doing so you will receive an award and their insurance will justifiably go up because they shouldn't be behind the wheel of a car.
Don't fuck about with this Sam - do it.
