"Got evidence? There's an app for that!"
With all of the new smartphones out there and apps that can do things now that we would have never dreamed of 20 years ago, there's one that may be able to prove your innocence or at least explain what happened in front of your vehicle.
I've shifted from using the GPS map feature and standard car-charger and converted it to dashcam mode as a default now and have already caught one near accident and one really bad driver in the short time I've been doing this. I fugure it may some day prove to come in handy and save someone's bacon, including my own, as it's able to tell the real story. It can also record your speed and GPS coordinates in real time and shows them during playback if the GPS is enabled.
Dashcams have been wonderful truth tellers for law enforcement and if the situation ever presents itself, it's nice to have video evidence working on your side to back up any statement.
So if you've ever had one of those times where you wish you had a video camera to record the person causing trouble on the road and wanted something to back up your words if it ever came to that, this could be the answer. Instant video camera without having to fumble around with one while you're trying to drive. But of course, driving safely is more important than getting something on video so no, I don't recommend driving any differently than you normally would just to catch something on video. But with a quick push of an on-screen button, you have started the recording.
Anyone else do this? The one I use is called "Daily Roads Voyager" I use on a Droid HTC Thunderbolt. Takes great, crisp video.
