Six 2000 square feet single family houses can fit on two existing 33 x 120 foot lots. The alleys are narrow streets and the streets become narrow streets to maintain green space. The density supports local amenities that you can walk or cycle to. The increased amenities provide more local jobs. It means you can get what you need locally without a car. Connect these neighbourhoods with effective public transit which is started by permitting these neighbourhoods around sky train stations and bus loops. Laneway housing is part of this solution. Design the neighbourhood as if you had not cars. It was done for millennia before cars. Give it another go.
