Traffic in Texas used to be pretty cool. On two-lane roads, slower motorists would always move to the shoulder to allow faster vehicles safe passage (If I recall correctly, driving on the shoulder in Texas is legal.) On the highways, most drivers knew what a rear-view-mirror was and used it to identify faster traffic, and move to the right lane. Also, packs of fast vehicles would rotate lead vehicles, sharing in the risk of getting a ticket.
But the Texas-Technology boom ruined all that. People from all over the country moved in and took over the roads with unfriendly, bad driving habits. Now the roads are jammed, just like here, with clueless cagers yacking on their cellies, driving the biggest SUVs they can afford.
The tech-boom also lured many Californians to Texas, trading their tiny Silicon Valley homes for luxury ranches. Now Texas is home to a growing number of California bikers, frustrated that they can't lane-share like they used to. I imagine they are the ones lobbying for it's legality. I hope they get it passed, so when I go home to visit family, I can lane-share legally.
By the way, there is some really nice asphalt out there. The are even curves, (albeit, none as tight the mountain roads out here) if you know where to look.
