Chapter 6. Drilldown
Get Ready to Push!
Driving cross-country in your car can be quite exciting—whether you’re stopping in small, quaint towns that are hardly noticeable on a map, flying down coastal highways with perilous views below, or enjoying the endless horizons of the plains. However, that state of happiness usually breaks immediately when you notice the low-fuel status icon has now appeared in your gas gauge.
This icon’s design creates more user mental load than necessary. If you’re in the middle of nowhere, and you haven’t seen a gas station or fuel information sign in miles, and now, on top of your uneasiness, you must calculate and predict how far you can go without running out of gas, you’re wondering:
Did this status light just come on?
Or has it been on for several miles?
How many miles am I going to have to walk to find a gas station after I run out of gas?
Do I have the appropriate walking shoes?
What you really need is the ability to quickly access additional related information.
