~10% of workers in my neighborhood were WFH before Covid. I'm seen a huge increase in hybrid or WFH since. Neighbors commute to DTLA via transit 2-3x/wk & enjoy the combo. Others who drive to Westside or Irvine hate it even though similar time SoCal job centers are diffuse but different industries cluster in different pockets. This is such a strain on 2-career couples who need to locate somewhere between 2 specialized jobs.
Hybrid is the best compromise for in person career growth & child rearing

Dropped off our car at Costco Tire Center for tire rotation. I learned from Nick Molden, CEO of Emissions Analytics, that EV tires have 2x the surface area (& 2x the VOC emissions) of tires from similar size cars. Image .@Toyota stopped selling Prius V station wagons, pushing buyers into the RAV4 Hybrid--taller, heavier, more dangerous, but carries the same amount of weight/volume.
Look at the difference in tire surface! Although similar MPG, the RAV4 tires emit more VOC & particulates Image
