Learn something new every day

I just had one of those moments where I questioned my intelligence or at least my skill of observation.

I have been a traveler for business for nearly 20 years and for most of my career I have been in automotive yet I only just learned something new about cars that you might find funny.  For sure this knowledge would have been useful these many years. 

Before getting to this new gem, let me quickly describe my typical car rental return: 

• I am usually late for a flight
• I did not select the "pre pay fuel" option
• I usually know where a nearby gas station is
• I almost always pull into a gas station with my car door open and my neck straining to see which side of the car the fuel tank access is on
• I pick wrong about 30% of the time. . . which usually means turning the car around

Please tell me I am not the only one that can't figure out which side of the car to offer up to the fuel pump?  Please?

Dan Brown would scoff and my inability to recognize the symbolism on the typical fuel guage in the typical car. (see below)

When did car manufacturers add in that little arrow?  Why wasn't it highlighted in drivers ed?  Why have I missed it all of these years?  Wow!  I feel really dumb.
