bike rider doored by taxi, page-184

Share the road, but not the same rules, now I know what the problem is.

*snorts* If you're going to try that argument, then why are trucks subject to different/additional rules compared to cars? I'm more than happy to have a reasonable debate, but seriously, that's just dogma.

"That's before you get into the practicality issues of fitting registration plates to bikes..."

Any less practical/difficult than fitting a camera?

Yes. How big is a camera? (Hint: look up the Fly6.) How big does a registration plate have to be in order to be visible from a reasonable distance? The two are nowhere near comparable.
