I'm surprised that so many posts are people saying they want this. I've never felt a strong preference for shady seats while traveling. Why do (many) people prefer them?

Well, last year I was doing a 1hr commute on a bus in Italy with 35 degrees outside and with broken AC :) It's not fun to have the sun pointing at you for 10 minutes straight I can tell you that

Earlier quoted context omitted.

It is funny in my language as we have the same word for both noon and south.

Is it French (midi)?

South in French is sud, while noon is indeed midi. However, the two words are the same in Latin (meridies, lit. midday, as in p.m. = post meridiem, etc.), so probably in some of the other Romance languages they do match?

Great idea. I'm wondering how dis you computed the sun postion in every area of the eath ?

Back in the 1980s when doing this we used a Naval Almanac - the US Navy navigation | star position formulas and data are all open source (as products of the US Government).

These days you can tease similar information from Celestia, Stellarium, and other astro projects.

Sun angle wrt a smooth perfect ellipsoid is one thing .. actual sun angle + shadows in the presence of mountains, valleys, forests, tall buildings, etc is a whole other ball of fun.

That would have seem to be something trivial to think about for anyone with a modicum of sense of orientation. I guess most people don't have that.

The sun doesn't rise in the East and set in the West though. And a random short route I put in had about 30 turns and all kinds of angles. Not everywhere is a US grid city :-).

Really nice idea and it works to an extent, but it doesn’t seem to use the bus routes — just sent me the quickest route via the motorway. Not sure how much of a ball ache that would be to implement though as I guess you would need to pair a lot of APIs or pay google out the backside

Currently OpenStreetMap routing API, would have to be replaced with the Google Maps Transit API.

OpenStreetMap routing API should provide routing with Car, Bicycle and Foot profiles. You might have to modify the API call to change the profile.

PS: There might be other free alternatives to using the main osm.org API which will be more reliable.
