Since we have shown that a "work from home" model is an available model for a majority of white collar jobs, is there a reason why city planners and civil engineers can't do a better job of placing markets/small business centers within biking and walking distance of a radial area of a suburban center? As far as driving is concerned, why not push for electric and end gas subsidies over a time period to allow for adjustment. Yes, I understand that we're in a desperate situation, but I also understand that too much change too quickly tends to have the opposite effect of what the original intention was in the first place. By setting up small, suburban "communities" that have many of their shopping needs met (a grocery, an open air market, a couple of whatever strip malls are called now, a school, an urgent care), proper bike paths and incentives on even plug in hybrids and work from home programs for jobs that didn't need to go into the office, we could focus on clean energy solutions for the grid - all of which are current technology and current lifestyles without much forced change, just rezoning and a continuation of what we learned during Cov19.
