The only downside to uploading video footage to youtube, is the typical driver comments, or keyboard warriors.
I used to record on a daily basis, and the one time I actually truly needed it, the camera didn't turn on, either the battery was dead or the card was full. Either way the bike was written off and I had minor injuries.
Luckily the driver in front of me had witnessed what had happened and followed the moron home to get his registration number and came back to me.
Now I don't know what to do. Either go back to filming, or just be grateful I walked away and it's all dealt with, and not think about the camera.
Whenever past instances occurred, I'd learn from it, such as riding primary (thank you CycleGaz), and other simple things like stopping listening to music.
