How hard will it be to set the gas pumps for more than $10 per gallon?

Factual Questions
1

When gasoline went over $1.00/gallon, they needed some hacks because the mechanical gas pumps of the day only had two digits for the price. Most stations set the price to half of the the actual. The attendant came out with a calculator and multiplied the amount on the pump by two.

With the electronic pumps we have today, it could be just a matter of changing software but the display of the price may not have a enough digits. Maybe they could eliminate the 9/10 of a cent to make room. will it be just software, or will they need to modify the hardware?

I wonder if they could do sort of the complement of that half the price per gallon times 2 and instead start selling gasoline by the half gallon or quart? If so, a pump limited to $9.99 per unit volume (currently one gallon) could sell gas for not quite $10/quart or not quite $40/gallon.

Technology has overcome greater challenges than this.

Start selling gas by the liter like most countries do. Problem solved.

5

That’s certainly where I got the idea. Although this being the USA we’ll almost certainly be doing it by the quart.

Dropping off that silly .9 at the end would give them one digit to work with]
