Plenty of police on the roads I use. Driving still awful and laws mostly unenforced.
Even if we keep within the law, we can still be delayed by unfair policing, like I mentioned. One locally-famous case involved a legal (with front brake) fixed wheel cyclist being detained for using an "illegal" cycle, according to the officer. So I'm in no hurry to see non-roads-policing officers cracking down on cyclists again because it'll slow everyone down and erode one of the key reasons people cycle: because it's a faster journey than car-then-walk.
I cycle because I'll never be allowed to drive. "Proving" to some folk that I can do what they feel can't be done. I was told I'd "never be able to cycle" for health reasons.
It's faster than walking over two miles round here. Shorter routes available when walking. And no worries over having to lock my trainers up when I get there.
I'm not a fan of the present road we seem to be headed down, forced onto off-road routes. I use a road vehicle, and as such expect to be allowed to use it where the law says I can. It's an attitude that has got me at odds with the local council. Who by the way don't have one councillour that has cycled since they were old enough to drive. The "cycling tsar" has never ridden a bike, but all route planning goes through her office.
If there is a change in the law, they'll have to go back on what they've already said. That being that licensing cyclist and registration of cyclists would cost more to implement than would be brought in by either scheme.
