Hovering? Like with a mouse?

It's still easy to forget that many people use applications on devices with only primitive input options available :).

Yup, if I'm looking for directions I'm probably on my phone, not at a computer. I guess others didn't get the point/joke, hence the downvotes?

I think this is great, but I can see it being potentially improved further if there was a temporary overlay of the physical map whenever you hover over a destination. Basically, I feel that completely removing the physical map is okay until you've picked a target. Then, having to click on it to be able to see what the route looks like (which streets to take, etc.) is higher friction than I'd like. Instead, imagine if…

Mapumental[1] does something like this - it shows how far you can get with public transport from a postcode in a certain amount of time.

Haven't fully thought it through, but I think such a projection would be unintelligible in most cases - it would probably only look remotely 'intuitive' if travel time would always increase with distance. For a real city, it would likely just be very weirdly morphed blobs of the map all cut up and smushed back together, with bizarrely curved roads, non-aligning roads & train lines, etc.

Now I definitely want to see that map, just for kicks.

Here's such a map for Singapore we created quite a while ago: http://xiaoji-chen.com/2011/isochronic-singapore/ http://www.chsommer.com/isosin.htm

I wrote my comment vaguely on purpose, but 19 hours later: yes, I meant touchscreen as primitive input mechanisms, compared to a mouse pointer.

In case it's unclear to anyone reading this, it's not just anecdotal: this has actually been studied http://www.washingtonpost.com/wp-dyn/content/article/2008/01...

Or not: https://www.eurekalert.org/pub_releases/2012-07/tu-ssm072012... https://link.springer.com/article/10.1007/s11199-008-9448-9

Right, I didn't mean to imply it was settled science, just that it was more than an anecdotal just-so story.

EDIT: Hold on, did you even read the links that you shared? Neither of them dispute the difference in preference/skill at different forms of navigation between genders. They just dispute the point that it's something that's genetically inherent (a point that nobody in this comment thread made). There's no need to immediately map everything you read to the closest political controversy and then draw the battle lines.

How about deform the physical map by a deformation field defined by ETA (i.e. stretch and compress)? e.g. https://www.slicer.org/wiki/Documentation/4.2/Modules/Deform... What would be cool about this is that it is still a map of the map, but the unit becomes time adjusted mile.

Perhaps you can go even further and try to make it so that any two points have pairwise correct distances, like in the Azimuthal equidistant projection? https://en.wikipedia.org/wiki/Azimuthal_equidistant_projecti... Perhaps there are metric functions where this is not possible (a quick proof eludes me...[1]), but approximations might be possible anyway. [1] Edit: actually it's quite simple. Any non-isotropic metric…

Edit2: Forget everything I said :) My geometry is quite rusty I guess. Not only any non-isotropic metric cannot have an Euclidean equidistant projection, any non-Euclidean metric clearly can't have an Euclidean equidistant projection. Metric spaces are defined by pairwise distances! What you can do however, is make the distance to 1 or 2 arbitrarily chosen points correct.
