This could really be a game-changer for me when we're allowed to travel again. I have a rare condition where a problem with brain metabolism screws up the signal to noise ratio in multiple senses, by day I'm quite photophobic and by night I can't see a thing thanks to "TV static" in my vision. Having a navigation tool that sticks to well-lit areas would be an amazing improvement over existing tools for me!

Out of curiosity, what's the name of your condition?

I have a friend where this could apply.

As trishmapow2 correctly guessed, I have visual snow syndrome. Whether it's a quirk of vision or an outright disability really tends to depend on the intensity, for some people it doesn't affect their lives at all but for others it's completely disabling because they can't read any more. Personally I'm quite lucky, I'm never going to drive in the dark or be good at things that require excellent vision but I can still hold down a job as a programmer.

Possibly https://en.wikipedia.org/wiki/Visual_snow. I used to assume everyone had this but since it doesn't really affect day to day life for me it was never a concern.

Oh, huh. I definitely experience all of those, though only the photophobia is really constant. I've also got a photic sneeze reflex, so I had just always chalked those two together as a sensitivity to direct sunlight, and didn't even think to consider the dots or floaters as odd or connected.

Same here, mind a bit blown atm.

Ditto. Additionally, Google Maps makes me try to cross streets that technically shouldn't be crossed by pedestrians.

Google Maps has functionality for reporting problems. I've done the same when it suggested an unsafe bicycle street-crossing and they updated the routing.

It may take a while for such information to make it to the map. https://www.theguardian.com/money/2020/dec/20/google-maps-po...:

“His problem was that the postcode for his east London flat was incorrect on Google Maps, so any driver using the service for navigation ended up not at his address, but in parkland at Three Mills Green, Bromley-by-Bow, half a mile away as the crow flies, but a mile and a half to drive.

What was an easily fixable error resulted in three years of frustration for Borghs, who first noticed the problem when an Uber driver took a wrong turn when taking him home.”

Google sure loves free employees...

As long as I don't have to pay obscene amounts for navigation, especially in the car, I don't mind.

In my Mazda, I only had to buy a $30 SD card from Ebay to make navigation functional

If I were you, I would stop buying random SD cards from the internet and connect to my devices, especially things like my car.

lol, fair point... but they can probably hack it remotely anyways...

Are you also of the opinion that you can't buy used phones?

> Are you also of the opinion that you can't buy used phones?

Depends, if you want a throwaway phone for a call or two that are not important, go ahead.

But if you're looking for a phone you'll keep for multiple years and you want the least possible risk of being tracked by someone else than who made your phone, then I would absolutely not buy a used phone.

Small problem as OK phones can be bought for ~$100 or less in most parts of the world.
