Eh, you're looking at it the wrong way. Would you walk in the highway or in the middle of a 4-lane road? No, because there's 3 ton vehicles there speeding around. Ergo you need proper separated infrastructure: sidewalks, etc. Likewise, why would you ride a bicycle there? You need proper separated infrastructure, i.e. a segregated bike lane. There's more than enough space for that, but drivers scream bloody murder if you take away one of their 8 lanes to make a bike lane or a proper sidewalk or a speed bump or whatever (even though this would actually ease congestion for cars!)
