I also merge this way and agree with the other comment that this is efficient by using all available pavement.

Also, when I do merge it is usually in front of a truck which is traveling slower than the rest of traffic, further using pavement more efficiently.

While true I make the trip of the people I "cut" possibly slower, I increase the speed of all the people behind me because I get past the jam faster.

Please take as friendly criticism, I like your other ideas and posts on traffic problems.
