Uber's car service lets you rate your drivers, but it also lets them rate you. The customer might always be right, but some customers are simply jerks -- and the system lets drivers know what they might be in for. Until now, there's been no way to draw out your customer rating from the app, but with a little Javascript magic, courtesy of Aaron Landy, you can cajole Uber's mobile site into spitting out your rating, out of 5. Log into Uber's mobile site, then open the console (for Chrome: View -> Developer -> Javascript Console from the drop-down menu), and paste some javascript code in. The browser will reload, and you'll need to paste the code again. Another reload, and a popup will offer up your user details and your passenger rating. The hack might even the odds a little: drivers have been able to see how passengers have ranked their rides for a while. It's like leaving feedback on eBay all over again.

Update: It appears Uber noticed the sudden influx to its mobile site and has now patched the JavaScript 'hack.'
