No, it really isn't. There isn't anything special about them, unless you're one of those people that believes a patent should be granted for an existing process simply because now it says, "on a computer".
I have some experience in this area of law and in my view it's how the "on a computer" aspect of the situation affects the power dynamic between Uber and the driver that makes it new and interesting.
In the model where contractors are dispatched to handle some task by phone the contractor is able to make counter offers to the company. Eliminating that through automation affects the legal test. The point I was replying to about the ability to choose jobs from different clients (Uber vs Lyft vs all the other edelivery services) also makes this different.
This is a complex area of law, which I'm guessing you haven't personally litigated, so you incorrectly compare it to the software patent issue.
