That was the whole point. I'm really concerned about where you're getting your information about Uber, because you said you've heard nothing but bad things (I've heard nothing but good) and that you're surprised they're less expensive (when being cheap is the whole reason behind the popularity).
Ok, given that Uber started out in San Francisco, I'll tell you what Uber means for a San Franciscan.
Back in the day, when you got out of the bars at 2am, you had to fight for a cab. People run upstream of traffic to hunt down the next cab. Sometimes you'd have to stand 20 minutes just to get a ride home. And when a cab did stop, you'd tell them that you live in the Sunset or even somewhere not as far like Pac Heights and they'd tell you conveniently that their shift is ending... or the credit card machine is broken all of a sudden. With luck you might be able to ride a puke smelling car that speeds through the hills of SF and you're holding on to your dear life. All while the driver doesn't speak a lick of English.
Compare this to NYC where its very easy to find a cab. Sure Friday evenings can be tough during rush hour and when people are headed out, but at least you see hundreds of cabs whizzing by. In SF, the number of cabs is just limited. You don't just put your hand up and a cab shows up in 5 seconds. It's easily a 10 minute ordeal even during the day. I've driven around looking for parking once at midnight and these girls paid me to drop them off 3 blocks away since they were in heels. That was seriously random. I thought I was gonna get mugged at first.
A ride across SF is anywhere from $15-$20 easily. Uber came about to offer not only cheaper service but higher quality service and most important of all...
availability.
Uber drivers also have to watch their rating. Any rating below 4.6 means they're kicked off the system. As a result they're super courteous now. They ask you about the temperature in the car, if you want water, etc.
In cities where Uber, Lyft and Sidecar are locked in huge battles like SF, where Lyfts are actually quite plenty too, there's a LOT of promotions going on. Lyft had a MATCHMUNI promo code that offered $2.25 shared rides anywhere in the city. Half the time, when calling a Lyft Line with my gf, we get no one else in the car. So it ends up being $4.50 (same as Muni for 2 people). I'd rather take a car than a pee smelling old POS bus with a bunch of crazies. Uberpool had some similar offer with a $5 offer anywhere in the city.
Just beware of surge pricing (Uber) or prime time (Lyft). Lyft tends to be cheaper for me, but only by a bit. I don't think I've taken a taxi since my last trip to NYC or somewhere I'm unfamiliar with.
