In a computer-implemented system, a plurality of inputs related to vehicle safe speed data for a first vehicle are received. These inputs include vehicle data received from one or more other vehicles proximate the first vehicle, historical data traffic condition information, predictive data regarding future traffic conditions, history data of a current driver of the first vehicle, current vehicle condition data, and current reaction of the current driver. Based upon the plurality of inputs, a recommended safe speed limit for the current driver is determined, and the determined recommended safe speed limit is presented to the current driver. The recommended safe speed limit is a calculated maximum speed, in real time, that the current driver should be driving.
