3. US route 99 (Indio Boulevard) was where the first yellow divider stripe was painted - over a century ago in 1915, an idea suggested by local physician Dr. June McCarroll, she wrote to the state dept. of transportation and it became a common road feature worldwide.

I thought the first center line was in Michigan?

The first centerline was painted by Edward N. Hines in the Detroit area in 1911 on a city street.

The first rural center line was on what used to be US-41/M-28 (now County 492) between Marquette and Neguanee, Michigan.

As for Dr. McCarroll, she thought of the idea in 1917, not 1915, well after Mr. Hines in any respect.  Hers came the came year as Multnomah County Sheriff's Deputy Peter Rexford thought of the idea in Oregon.

The concept in Europe may be even older. http://nathanjbaker.com/rexford/1947%20Rexford%20Retirement.pdf

I see that Desert Man actually specified a "yellow" centerline in his post.

I'm not aware of any yellow centerlines in the US until the 60s, unless other places had been toying with the idea?

A piece of a Soviet satellite, Sputnik 4, landed here, in the middle of one of our main streets. We have a cool festival to celebrate it every September, around the time it landed, and we even made a replica of the piece which we keep at our local art museum nearby.

As for anything road-related, we have a carferry that runs across Lake Michigan and is part of US 10, making it one of the only highways in the country connected by ferry.
