1. A method of limiting a maximum road speed of a vehicle, the method comprising:
limiting, by at least one processor of the vehicle, a road speed of the vehicle to a first speed;
receiving, by the at least one processor, a request for an override for the vehicle to exceed the first speed;
determining, by the at least one processor, a number of times the override for the vehicle to exceed the first speed has been activated during a current activation assessment interval; and
in response to determining that the number of times the override for the vehicle to exceed the first speed has been activated during the current activation assessment interval is below a threshold number of activations per activation assessment interval, wherein the threshold number of activations is greater than or equal to two activations per activation assessment interval:
limiting, by the at least one processor, the road speed of the vehicle to a second speed higher than the first speed for an activation interval, wherein the activation interval is a predetermined, fixed distance when the override is activated and wherein the activation interval resets each time a condition for the override is enabled;
causing concurrent display of distance-based statuses of the current activation assessment interval and of the activation interval; and
responsive to expiration of the activation interval, limiting, by the at least one processor, the road speed of the vehicle to the first speed after the activation interval.
