The simple example I gave in a sibling comment is that in India you have the option to call a tuktuk or a scooter which has a whole different guide set, flow, more screens. And lots of different airport specific, town specific, county specific, country specific regulations about things that need to be shown, taxes, etc. For all of that to be seamlessly available as you travel you need to be downloading a pretty large bundle upfront. Else you end up in a situation where you need the service’s reliability the most (travelling in a foreign country) and not being able to use it easily (because you have crappier data from bad infrastructure or a cheap SIM card and can’t download a location specific bundle)
