The quality of google maps routing has become terrible over the past few years. I sometimes visit a few Indian cities on work. There are many places that you can walk to. Interestingly, Apple maps on my iPhone shows me at least 2-3 good walking routes, while google maps tries to get me killed on busy thoroughfares or tells me to walk across eight lanes of peak-hour traffic.

When taking a cab, google maps increasingly routes me through narrow roads, streets that can only accommodate a bike, or the wrong way in one-way roads. Apple maps usually gets it right. Sometimes google routes are just plain wrong - it takes me to the wrong destination - and I'm left scratching my head as to how the heck any algorithm that worked earlier could do this now.

I remember a time when Google maps was not this terrible.

A few years ago google maps told my wife and I to "use the left lane to turn right" at an intersection of major 5 lane roads. The diagram even showed a car in the far left turn lane making a suicidal right across all the traffic. I couldn't believe it. Not a new road either.

I can understand a bad sequence of directions emerging from the process, but issuing an individual instruction that on it's face is dangerous and wrong?

Jumping in before someone from Melbourne tells you about hook turns.
Wiki: https://en.m.wikipedia.org/wiki/Hook_turn

> A hook turn (Australian English) or two-stage turn (British English), also known as a Copenhagen Left (in reference to cyclists specifically),[1] is a road cycling manoeuvre or a motor vehicle traffic-control mechanism in which vehicles that would normally turn from the innermost lane of an intersection instead turn from the outermost lane, across all other lanes of traffic.

Jeepers! First I'd ever heard of those. The logic is flawless, but they'd be terrifying to encounter blind.
