Distance Left For Gas Filling | |||||||||||||||||
Normal Fuel gauge shows the amount of fuel in the tank in terms of Empty to Full. I would suggest to have a gauge which shows the distance left according to the level of fuel. Whenever fuel reduces this gauge would show the distance remaining for next fuel filling. It would be similar to normal speed gauge with distance along the gauge.

The amount of fuel consumed is responsive, not only to distance, but to other factors such as acceleration, idling, stop and go traffic, etc.
While sand's comment is true, I think this is not a bad idea. Of course it will only be an estimate, but even that could be helpful. A really sophisticated system could take into account where you are driving (using GPS), traffic conditions, weather, and your personal driving habits.
Another problem is that fuel gauges are typically very inaccurate. However, it should be possible to design a better gauge mechanism.
I've driven plenty of rental cars with a DTE distance-to-empty feature on their 'computer.' They're always really conservative. It really turns out to be not-that-helpful, because we don't really have a real-time way to know if we'll try to make it home and buy gas the next day or buy it on the way home tonight.
Also, in terms of driving ease, maybe a 'time to empty' would be more beneficial.
On the BBC show 'Top Gear', they drove a Jag diesel over 120 miles past where the computer showed DTE equal to zero.
Yup, they have been out for years, some better than others. As for the Jag going 120 miles past 0, sure better than the other way around!
Most of the cars I've drive with DTE are fairly close. They are pretty much equal to a normal "low fuel" idiot light. I think they use DTE = 0 in place of when the idiot light would normally come on. I know my truck still has about 4.5 gallons left in the tank when my light comes on. Of course, this doesn't get me 120 miles, it only gets me to the next gas station.
