slow down – save lives

Driving 3.3 miles on 35th Ave SW from Fauntleroy to SW Roxbury takes 5 minutes at 40 mph, or 6.6 minutes at 30 mph, if you could make all the lights and no traffic slows you down. Assuming that was possible, how important is it to get there 100 seconds faster? It is worth risking lives?
