Brian Yudkin,  Duncan Kay,  Jane Marsh, and  Jackson Tomchek writes for the Rocky Mountain Institute:

Beyond the climate consequences resulting from transportation emissions, this high baseline of driving has given rise to a range of societal ills in American cities. These include inequitable access to destinations, disconnected communities, and the nearly universal frustration of congestion. Our highway system has served to segregate populations, heightening long-standing injustices, while high costs of living and limited housing options continue to facilitate sprawl away from city centers.

RMI analysis indicates that the United States must reduce VMT by 20 percent before the end of the decade to limit warming to 1.5°C—and this remains true even under ambitious EV adoption scenarios.

The article continues to details some of the interventions that can reduce vehicle miles traveled (VMT), like pricing signals, ending highway expansions, and transportation demand management and provides an infographic to illustrate the effects of some of those interventions.
