1. A method implemented by one or more data processing systems, comprising:
receiving, by the one or more data processing systems, data produced by one or more telematics sensors in a vehicle, wherein the one or more telematics sensors comprise an accelerometer;
determining, based on the data and by the one or more data processing systems, a plurality of telematics data items that are sampled at a plurality of sample times, wherein each of the plurality of telematics data items comprise a forward acceleration of the vehicle, and wherein determining the plurality of telematics data items comprises determining the forward acceleration of the vehicle based on an output of the accelerometer and an orientation of the accelerometer relative to the vehicle;
for one or more of the plurality of sample times,
accessing, by the one or more data processing systems, a given telematics data item sampled at a given sample time;
determining, by the one or more data processing systems, that the given telematics data item satisfies one or more data validity conditions;
in response to determining that the given telematics data item satisfies the one or more data validity conditions, computing, by the one or more data processing systems and based on the given telematics data item, a fuel consumption amount at the given sample time; and
determining, by the one or more data processing systems, a distance traveled by the vehicle from (i) a previous sample time that is prior to the given sample time, to (ii) the given sample time;
computing, by the one or more data processing systems, a total distance and a total fuel consumption amount, with the computing based on distances traveled and fuel consumption amounts for the plurality of telematics data items;
determining, by the one or more data processing systems, a fuel efficiency score based on the total fuel consumption amount and at least one of: the total distance; or a total time for the vehicle to travel the total distance; and
providing the fuel efficiency score to the driver.
