4G on a Moto is basically the worst case scenario but also how half the world interacts with the internet at large. If you're going to pick one scenario that describes a lot of users, they're pretty much dead on.
I think 4G doesn't tell the whole story, especially in several businesses that target users in specific conditions (e.g. tourism, where your users have poor unstable 4g) or specific markets withpoor avera8ge mobile connections.
