Lyft's vision would only have three lanes for general-purpose driving. The rest would be intended for, well, everything else. There would be two autonomous bus lanes, and a loading zone would give ridesharing passengers a dedicated pickup space. Logically, many of these rides would be self-driving cars. You would also see two bike lanes, wider sidewalks and more landscaping. Lyft is clearly betting that you'll be more likely to forego a personal car if the alternatives are treated as first-class options, and that increased autonomy could handle many more commuters. The bus lanes alone would handle as many as 35,000 people per hour, according to Lyft's estimate.

This doesn't mean that Los Angeles will implement Lyft's redesign -- it's only an idea right now. With that said, it's likely to find a receptive audience. Lyft is already working with the Southern California Association of Governments on a campaign for more intelligent streets, and Los Angeles is planning for half of all trips to rely on something other than a car by 2035. In that sense, the challenge isn't so much phasing out LA's notoriously car-centric focus as it is transitioning at the right moment. Self-driving vehicles are still in their infancy, and officials might spark more than a little outrage if they reduce lane counts before most Angelenos are ready to ditch their own vehicles.
