StuartG said:Correct, average at best. That's the point as a cyclist you should expect most folks passing a speed camera to be not looking out for you.
Are you sure 'good' drivers don't do the same (or if not, they actually exist?). An issue with motorists is that even a 'good' driver is more of a danger to other road users than a 'bad' cyclist or pedestrian. And I'm less skilled cyclist than driver ... perhaps I should just stay in bed?
As I said above a good driver is always scanning and planning so there should never be a situation where they have to choose between seeing their speedo or a cyclist. All drivers are humans so even good ones will make mistakes, however cars are not going to disaapear from our roads tomorrow so drivers recognising they are not very good and trying to do something about it helps. Advanced driver training is available (£139 for a course) all over the UK http://www.iam.org.uk/which will dramatically reduce your risk of being involved in an accident (either your fault or someone elses). Probably a better long term option than staying in bed, although it may mean a few early rises on a Sunday if its like they do them round here

Problem with most drivers is they only look at the 4 SqM directly in front of the car, which is why so many drive round with their front fog lights on when its not foggy.
