I’ve only used Uber once, in San Francisco, but it was a great experience. What made it great however was not the car, what makes Uber great (to me) is two things:
1. Hailing a cab to you, via an app before you step outside.
2. Never having to open your wallet to pay for the ride: get in, get out.
Those two points are what make your standard cab more of a hassle. So I am all for a cheaper option. I don’t know if Seattle has the hybrids yet, but I did get an email saying that the SUVs are available. I sincerely hope that Uber forces cab companies to be less of a pain in the ass.
