The Uber app keeps pushing notifications to advertise fast food. This is so annoying since you need alerts enabled for when your ride is on its way. As I am a very infrequent customer I just uninstall the app, and reinstall it if I need a ride.
This is why I use Lyft, and only install Uber when I'm traveling to a country where Lyft doesn't operate.
You don’t actually need alerts enabled for your ride - I just get ready, order my ride, then have a seat in a chair where I can see the road and do some reading. When my ride shows up I leave the house.
