Exhaust processing of current trucks basically doesn't work with a city driving profile (~high idle fraction, very low loads, average speed 15-25 km/h).

  They need periodic runs on decent speed roads, I’d have thought this road itself would do the trick. Presumably it doesn’t run at 20kmph.

    For several hours a day the people using this road would be ecstatic if it were that fast.

    The I5 does often run at those speeds in this location, which is why they want to add lanes here.
