Nikita is off for some school trip. Was a good enough excuse to get some sun on the beach!

If anybody is not familiar with interstate highway I-16 in Georgia, it connects Savannah to Macon and pretty much goes like a straight line east-west. There are virtually no towns or cities in between. As a result the 120 mile or so highway has a consistent speed limit of 70 mph.

Sharmila and I were coming back from Hilton Head on this highway. Somewhere in that highway, I noticed something interesting. The display on the rental car dashboard informed me that the speed limit was 40 mph. (see the top middle portion of the picture) I was not in a construction zone and the highway was totally clear.

It took me some time and experimentation to understand what was going on.

Can you guess why the car was giving me completely wrong info (suggesting 40mph in a clearly 70mph stretch)?

If you want a slight hint, check out the other displays on the dashboard in the picture.
