Yeah, those are referred to as "goosenecks". Not really a drip tip, but an extension to be used between a drip tip and your battery device. The idea was conceived when a vapor was involved in a bad auto accident, and realized had the accident occured at the moment that he was
vaping he could have had his PV smashed into his mouth.
The gooseneck adaptor allows you to vape while the battery device is a safe distance away from your face. It is useful for other circumstances, too, of course. I've never used one myself, but I think they are a good idea to use while driving.
As far as a flexable drip tip, the only one that comes to mind are the Knucklehead drip tips. They have an elbow joint which allows it to flex in nearly any direction. I have a couple and they are among the most comfortable tips that I use.
