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
Would you get significantly different results? I'd expect this would work OK even if you assumed travel in a completely straight line - unless you're tacking like a sailboat, you're going to spend most of your time travelling close to the overall direction of travel.
