The lane by lane is more harm than help IMHO.

You often get an instruction like "use the left 2 lanes". But where you are when the instruction is given, the leftmost lane might be a forced early left turn. If you're unfamiliar with the location, this requires a lot of extra cognitive load, vs simply not giving that specificity at all.

As well, traffic conditions change rapidly and the lane by lane doesn't account for that.

In some easier situations, it's great, but it's a negative in more complex situations.

I’ve found their reporting mechanism for incorrect directions to be very easy to use and that they are responsive to the suggestions. Please leave a marker for the next poor soul who’d get snared in that trap!
