Well...
The cynic in me says that it's economics or laziness or apathy on the parts
of the car companies.
Is there a way to get linear output?
ABSOLUTELY...piece of cake for a resistor maker. BUT:
They would have to have a different sender for any change in size and shape
of fuel tank. Car companies don't like to pay for X number of 10 different
items, when they can get 10X of one piece for a lot less money.
The bottom line: Is Ford losing to Chevy or vice versa because their fuel
guages don't read spot on?
