LA is notoriously car-oriented, but is it different in that respect?
Those are really next level because they are essentially bike freeways; completely separated from car traffic (no intersections because the river & bike trail go underneath road bridges).
In fact, it's not only safe and fun, but also much faster than driving during rush hour.
But yeah, when you can find an empty/slow side street it’s hundreds of times better than a bike lane right next to high speed traffic and cars cutting you off.
Apart from that it is a net positive for me and I wouldn't stop. You have to die one death they say and if it is lung cancer or COPD for me, so be it.
Just wait til you try it with a 7 year old who adores you and just can't wait to go biking again. Or with a 12 year old, just chatting about life's paths. What a blessing.
Paradise.
