The problem is, people are using solely what3words for location. Every single call recording to emergency services doesn't use any other information.

The odds are around 1 in 24 that you hit one of these squares in London.

Yes, that's pretty much the definition of incorrect.

Old skool! Those were the days :)

A design requirement of the app is it works offline.

Your surface area is totally incorrect.

Only with a ridiculously long word list containing plurals and words people can't spell.

Yeah, multiple MRT members have contacted me to say this is a real struggle. If someone is on the move, it's virtually impossible to work out what direction they are going.

It's promoted for use in search and rescue, so other bands are in use.

Why 3 words? Why not 4?

You would still get high densities of cells which share two words being present close together, leading to any issue with the third word causing a confusing location.

The word list already is 40k long. That's beyond most people's vocab and includes really awkward to spell words.

IMO, if the solution is to use words, then What4Words would have had a word list of less than 3000, resulting in a word list with less confusable words and more accessible to children and people who struggle to read or write.

Two reasons: 1. It needs to be reversible so you can go from words to lat/lon. 2. They wanted to use shorter words in cities, so the distribution of low n didn't want to cover the full range of m. (this could probably be solved by some sort of banding though).

Yes, sorry, added that bit on my phone when out and about and made a mistake. Corrected.
