The online commenters have showed me that they think it's clearly the riders fault since he must not have been paying attention. I wish we could set up some sort of experiment without their knowledge.
-Put these expert drivers in a car at 110kph in the left lane on any busy major highway that does not have a left lane shoulder
-Have them following another vehicle with a roughly 2-second gap. Hardly anyone leaves this much room but lets just use that.....
-Have the lead vehicle swerve out of the way at the last possible moment to avoid a large concrete block that is centered in the left lane.
-Record the percentage of drivers who are able to avoid hitting the concrete block.
-Or we could make the block out of foam that looks like concrete... whatever.
I would estimate no more than 25%
A truck towing a trailer, that was infront of the bike, made it around the stopped car.
Sure, there are several ways.... and one of them would be if the rider was paying attention.. and wasn't "gesturing" the girl.
To make caboose's experiment more interesting, arrange for the lane adjacent to the truck/trailer in front to be clear so that it has a clear path to swerve right, but arrange for another vehicle to be adjacent to the driver being experimented upon, so that they can't swerve to the right without hitting it. Give the experimentee 10 seconds to take the correct action of either speeding up or slowing down so that they are not adjacent to the other vehicle. Most people won't take the opportunity, most people won't even recognize the hazard of being directly beside another vehicle, and I betcha most people will hit the foam/concrete block.
