Is anyone currently using or thinking about getting a dashboard camera for your vehicle? I've got a GoPro Hero 3+ that I've used for this and I've used my iPad or iPhone for it. I witnessed an accident last week where I clearly saw the driver of one car leave her lane and hit the side of another driver. The two drivers, both women were arguing and almost getting ready to fight. The taxi cab that was behind me had the incident on his dash cam. Even with my car in the way, you could see the vehicle leave her lane causing the accident. Another day, I saw a person riding on the can on a Red Bull little truck. Would have been a very funny video. If you are using one, what are you using? Does it start with the vehicle or do you have to turn it on each time?
