Thank you for doing these experiments. They have been very interesting to learn about.

However, despite your conclusions, I'm not convinced that leaving these gaps will help ease traffic congestion. The reason is that ahead of you still exists a traffic jam that you cannot change or ease. It would be impossible to do that from behind.

Also, in the Baltimore-D.C. area, a few motorists do leave gaps (not sure if they do it because of your experiments), but this is futile, as those gaps are quickly filled by other motorists. There is just too much traffic in this big metropolis to let any gaps in traffic exist for too long. To do this would actually be an inefficient use of the lanes.

This is why we need other solutions to ease traffic congestion. If you'd like, please visit, leave comments, and share with others.
