Here is the thing where it falls short though:
the guy at the front riding the wave really slow to "help lane locks" will also get merging traffic many many time right in front of him (people taking advantage of the free space), as a result, it won't help that lane but only make it worse if you're stuck behind such driver (or truck).
So if everyone stuck to their lanes, didn't change unless extremely necessary, and played the wave-canceling technique, it would work.
In other words, this will work when cars will be driven by computers hooked together via apis and maybe a traffic controller. I'm not signing for the beta.
