Petrol Meter For Vehicle, When We Will Make It???????????

Petrol Meter For Vehicle.

Hello Everyone today, a question striking on my mind that we people saying we have many scientists we are inventing many this day by day we are growing in science, we have reached on Marsh and etc..etc... 

                                    But today when i was filling fuel on my vehicle i don't no exactly how much fuel in vehicle and how much i should fill, vehicle company provides a indicator for fuel but these are not correct because its not give perfect information about fuel....                                                              

  I cant understand why not yet a petrol meter which will show  accurate information about vehicle fuel, it will give us two profit.
1. We can always know when we should fill the fuel.
2. We will safe from petrol pump cheaters.
