Easy to use, safe, very handy. Ive never felt overly uncomfortable (more than you would in a strangers car) or threatened in any way. Most drivers have been quite helpful and friendly, in fact. I do wish there was a way to communicate with the driver via message or call beforehand to let them know of any special situations or if they are for example, comfortable transporting shopping bags. Also, I use an iPod to call a car so I dont see an issue with location services being on. As for company ethics, I dont care honestly. Uber provides a great service at an amazing price and I would recommend this to anyone.
