The disclosure includes embodiments for implementing a function update for an Advanced Driver Assistance System (“an ADAS system”) of a vehicle. In some embodiments, the method includes the vehicle receiving a Dedicated Short Range Communication message (“a DSRC message”) on a 5.9 gigahertz band. The DSRC message includes digital data that describes a driving situation of one or more other vehicles in relation to the vehicle. The method includes determining, based on the driving situation described by the digital data, to implement the function update for the ADAS system by reconfiguring a Field-Programmable Gate Array (“an FPGA”) of the vehicle which is operable to control an operation of the ADAS system. The method includes reconfiguring the FPGA of the vehicle to implement the function update so that the FPGA controls the operation of the ADAS system in a manner that conforms to the function update.
