Over 40% of Cambridge residents work from home. Many more are perfectly fine walking, biking or taking the T to work. The idea that it should be illegal to build apartments that cater to this majority doesn't make any sense. There's plenty of housing in Cambridge with off-street parking for those who would like it.
Parking minimums don't provide free parking - they just bake the cost of parking into the rent and everything else. They're not even primarily about "choking out" car usage - it's somewhat confusing I get it but it's a housing policy first, not a transportation policy.
