Nope neither he nor I are as compelling as then factual evidence - that the person in question was prosecuted, was convicted and did receive a custodial sentence. His opinion would have been far more compelling had it proved not possible to secure a conviction ... but it was.
And yet you don't know what issues with the law he was referring to, you don't know the details of the case. Your assumption that reading a bit about it on here makes you exactly as expert as the presiding judge in the case is almost funny.
I suspect given your knee jerk reaction that the measure, an amendment in a wide ranging bill that may well get cross party support, is somehow 'redmeat' is due to you somehow seeing it as an attack on you as a 'cyclist'. There are not hordes of slavering Conservative pedestrians howling for the blood of cyclists, and it certainly wouldn't be satisfied by a fairly obscure change in a portmanteau bill.
I don't know enough about the details of the law here to say there definitely isn't a problem, and that the presiding judge has queries means I would like to know more. I'm also wondering why we might have legislation on dangerous driving, and whether this is related to similar issues in cases there which were addresses by that being introduced.
