It cannot be called line sharing, since unwritten rule says that splitting is when you ride between lanes separated by dashed line.
Also as far as I remember crossing solid white line is generally discouraged (i am not sure whether its a violation thou). But looks like you crossed it.
Practically, you were passing on the right, using the shoulder/bike lane, which is a violation.

I was riding my scooter up to campus and rode in the bike lane to pass a bunch of cars queued up at a busy intersection. The LEO was standing on the corner of the intersection when he saw me. He pointed, told me to stop, and cited me for 21209(a), driving in a bike lane. I didn't argue, just said I was making a right turn. He said "No, look, you were way back there."
Yes I was in the bike lane, but this is legal for 200 feet before an intersection in preparation for a right turn (which I was making.) I can't remember exactly when I entered the bike lane, but it was probably on the 200 foot mark give or take 10 feet.
I'd like to fight this - beyond about 200 feet the officers line of site is blocked by a row of trees, so even if I had entered the bike lane beyond 200 feet, he wouldn't have been able to see.
So do I have a case? Are these pictures sufficient evidence, along with a well-written statement? (TBWD?)
Some pics: Red X is where the LEO was standing. Blue arrow shows my intended path through the intersection.

Officers viewpoint: 200 feet is about where the close side of the white van is parked.

Did you measure 200 ft? From the intersection? By what method?
Measured with google maps scale and verified with a tape measure.
When lane sharing is it specified which side of the lane you are allowed to share? I was definitely sharing for some distance before entering the bike lane. (Or is that illegally passing on the right?)

Because I wanted to see, I took it upon myself to check your google map logic. By my calculations on the 100ft 50ft and 20ft scale, you were well over 200ft before hitting the limit line of the intersection (in accordance with your original post). That doesn't take into account that the google image isn't directly downwards so scale is slightly off. I used the 20ft zoom so that it would be more accurate.

The law on lane sharing isn't defined, but the passing on the right law is.
Also because I'm fairly sure the citing officer has riding buddies on this board and that it's been screen capped, any defense in court will probably be dismissed by your admission of guilt.
At this point even a Trial by Written Declaration probably wouldn't help you.

Oh great, just what we need.

365. An "intersection" is the area embraced within the prolongation
of the lateral curb lines...
21209. (a) No person shall drive a motor vehicle in a bicycle lane established on a roadway pursuant to Section 21207 except as follows:
(3) To prepare for a turn within a distance of 200 feet from the intersection.
I'm not sure it makes any difference in this situation but it's not clear to me that any of you are measuring the 200 ft from the correct starting point.

Actually, it would be nice to have some legitimate laws on what we can and can not do. In regards to lane sharing/splitting. Since there is no official laws written on such.
If you look at the street markings, the bike lane starts and ENDS WAY before the right turn lane AND if you were IN IT at any time, you were way before the right turn lane. LOOK at the street markings.
PS no sympathy from me. I hate motorized vehicles of any sort in bike lanes.
The last thing Kalifornia needs are more freaking laws on the books.
BTW, aren't all laws "legitimate"?
