Nope, Caltrans calls them "rain grooves". What you are indicating nasphere are commonly called "semi tracks". Those are hard to get out of because it seems the track of the Insight is exactly the same width between the inside measurement of the semi tires (in track width.) The worst ones I've seen are in Oregon. All I try to do there is put one side of the Insights wheels (Prefer pass side) in the groove and let the other side ride on the crown between the "semi tracks". The vehicle will have a habit of trying to pull to one side or the other, dpending on which side in in the grooves.
