> but I doubt you are thinking of someone driving 50 mph in a 45mph zone. That is not the type of speeding that kills I know you're pulling this up as an example of a small infringement, but there are studies that quantify the fatality rate as a function of velocity. The numbers you picked are right in the steepest part of the increase. Using equation 2.3 from [0] (with conversions from mph to kph), there's a 64% chance of fatality at 45mph, but a 83% chance of fatality at 50mph.
