If you limit the speed of cars inside the city from 80 to 50 k | Health & Doctor

If you limit the speed of cars inside the city from 80 to 50 km/h, you only lose about 30 seconds per km of travel or 7 minutes for an average trip of 18 km, much less than your brain draws

But at the same time the survivability at the time of impact between 30 and 60 km/h impact is multiple.
