Cambridge wanted a big drop in car ownership by 2020. That hasn’t exactly happened.

With six subway stations, multiple bus lines and bike lanes, and compact neighborhoods everywhere, Cambridge offers plenty of ways to get around without a car. And increasingly, many of its residents are.

Yet even Cambridge — which took up the anticar cause decades ago to oppose a proposed interstate highway through the heart of Central Square — can’t get more residents to give up their vehicles.

The city appears all but certain to fall short of its 2020 goal of reducing the ratio of cars owned by Cambridge residents by 15 percent from 1990 levels. The target, set in 2014, was to lower ownership to about 0.8 cars per household, but with about a year left on the clock, Cambridge is less than halfway there.
