Accounting for driver reaction time when providing driving instructions

A method for providing navigational directions to a vehicle, the method comprising:

• receiving, by a processor, global positioning system (GPS) data indicative of a current location of the vehicle;
• directing, by the processor, the vehicle to a desired destination using a first driving route;
• receiving, by the processor, at a first time, data indicating that a new route for the vehicle is requested;
• determining, by the processor, a first location of the vehicle at the first time;
• determining, by the processor, a time period to wait after the first time at which to determine a second location of the vehicle if the new route is taken, wherein the time period is based on an estimated driver reaction time to implement the new route and a path of the new route, wherein the estimate driver reaction time is based on past driving performance of a driver of the vehicle or past driving performance of a plurality of drivers;
• determining, by the processor, a second location of the vehicle after the time period has passed;
• determining, by the processor, based on the second location of the vehicle and the new route, a second driving route;
• and
• redirecting, by the processor, the vehicle to a second driving route.
