Streetcar tracks cause false lane departure warning?

Philadelphia has street cars.

driving through an intersection with turning lanes (for the intersecting road) also causes mine to go off.....

You're right. I was under the impression that Toronto and San Fran were the only cities in NA with streetcars but Philly and Boston appear to have them as well.

Guys. Really?

I think the following cities in Canada and the U.S. have "heritage streetcars" or light rail running in street:
Atlanta, Baltimore, Boston, Buffalo, Dallas, Houston, Los Angeles, Memphis, Minneapolis, New Orleans, Philadelphia, Portland, Salt Lake City, San Francisco, Seattle, Tampa.
Toronto (I don't think Calgary or Edmonton have street-running sections which are shared with cars)

There may be more, there are certainly more light rail systems, but I'm not sure which have street-running sections.

There are also plenty of places with abandoned rail still in-street, and at least one place with a main-line railway running right down the street: Oakland, CA.

I was driving through a construction zone last summer and thought about autonomous cars. In construction zones, you have to rigorously follow the cones and ignore the multiple lines that have been painted as the lanes change during the construction process. This will be a challenge for self-driving cars, much like the rail lines.

Exactly. I'm doubtful that such things can ever be completely automated safely. Heck, how is a car supposed to keep in a lane when the lanes aren't visible, due to snow or salt? I've seen roads in mid-winter in some places where the road surface is basically white, and it's very, very difficult to see painted white dashed lines. And what about when half the lane is occupied by a snowbank?

Airplanes are capable of auto land when all the required equipment is in place. But it still requires specialized training and the ability of the pilots to take over at any point. And it's rarely used - generally only when a landing would not otherwise be possible (due to low cloud). And that, to me, is a far simpler problem than navigating all possible road conditions everywhere.

I used to work in software. Call me a skeptic.

Once AI is here it'll be smart enough to autonomously drive us around in all these situations.

Mine goes off with pavement crack fill lines all the time if they are parallel to the lane line.
