Minor neighborhood roads are necessary so that residents can get home, but they were never intended for mass through traffic. Traffic near humans increases risk to life by way of accidents as well as localized air pollution (living within a short distance of a major roadway is extremely unhealthy in the long term, independently of the issue of regional air pollution that covers all of socal). Using roads for a purpose they were never engineered to serve is not the way out of LA's traffic crisis. But sure, saving two minutes on your commute is worth the cost of running over a dog or child now and then.
