Uber is different because you use an app instead of calling a person on the phone to order a cab. Furthermore, with an Uber you don’t even have to talk to the driver because they already know your destination.
DoorDash is similar: you use an app instead of placing an order over the phone. This is meaningful enough that many people switched to it even when their favourite restaurant already had delivery because they didn’t want to talk to someone on the phone.
The issue with electrifying rail networks is that it’s very expensive and modern diesel-electric locomotives are already over a hundred times more efficient than trucks. So while it does reduce emissions to replace a diesel locomotive with a fully electric train you’re far better off getting hundreds of trucks off the road and adding one new diesel-electric locomotive!
