I noticed this compilation presented a fair and balanced viewpoint, in that you could plainly see that there were a few motorcyclists at fault as well as motorists. Wearing a helmet is half the battle. We also need to be observant, observable, and as predictable as we can be. The more oblivious and distracted the motorists are, the more invisible we bikers become. I'd say if you're not sure a motorist has seen you, pretend he didn't. But, as the video shows, we ourselves have to do our best to make sure we have seen all the motorists and other dangers which might be heading our way. And remember that each risk we take out on a road could be our last. The public thoroughfares are just not a healthy place to take risks.
It's a big job, going out onto the road these days. If you figure everybody's out to get you, just like they're all out to get each other, you might be able to make it to point "B" okay. (Being in an accident can make a guy really paranoid, ya know.)
