I’m referring to urban highways where opposing lanes are right next to each other, like the sort of spacing that you would need for a barrier next to a bicycle lane. Those cable systems are only installed in cases where there is generous clearance for debris, which is not applicable for the roadside bicycle lanes we are discussing.

Admittedly it would be much safer for those in the bike lane if we dug a W profile ditch in pace of the car lanes. For some reason I don’t see that happening.
