Taking the one example above, I think it would be impractical to have to have a full jury trial if breathalyser or blood test evidence of high blood alcohol levels are present. I'd like to think that, even in such circumstances, the option of a full trial should be made available to the person being charged, if they felt they wanted it. However, if found guilty (which would be almost a certainty) they would have to pay all court costs.
JBR, perhaps you've misunderstood the reason for trial by jury, maybe your lack of personal experience is the reason.
Anyone who elects to go to trial at the crown court (if election is available) are tried by a jury IF they plead "not guilty". A "guilty" plea does not require a trial, merely a sentence, by the judge.
So, in the event of overwhelming evidence an accused can still elect to plead "not guilty" and thus "trial by jury" but they would need to convince the jury of the fallibility of the evidence. I doubt that they would receive such advice from their counsel.
I'm not sure if costs are based on the need for a jury, 'cos they receive so little compensation. I think the costs are based more on the number of days the trial takes, and other such associated costs.
Edit: As an after thought, I suspect that recent changes to "Legal Aid" means that financial assistance is more forthcoming in Crown Court affairs (i.e involving juries) than in Magistrates Courts.
