Decide by steering is just stupid, how did this happen?
What was the rationale for removing this feature? There was no reason to. The "decide by steering" feature could still be added and operate when "let me decide" was selected rather than "always take the fastest route".
As others have noted the green alternative routes often appear at the last minute when it's too late to actually change direction, and can serve to disorient and distract the driver. But fundamentally the whole idea behind this is mind-bogglingly stupid, we have computers that are able to make decisions on the fly and direct the driver to their destination the quickest way possible while adapting to changing traffic conditions. You LITERALLY HAD THIS WORKING. There was no reason to remove it, you've just made your product worse for no reason.
