Why 37 degrees?

Have you noticed that cages in the last few years have had either a visual emblem appear on your display or an audible alarm, possibly a bell ding when you are riding along on a colder day. The emblem may appear as a car lane with an "x" through it. If you pay attention to these warnings they arrive when the outside temperature reaches 37 degrees.

Have you asked yourself why a display would come on at 37 degrees? Do you know why it comes on at 37 degrees? Well it's simple, when the air temperature is at 37 Black Ice can form on pavement. The warning is just letting you know you are in conditions where Black Ice may become an issue.

Why a bell ding without an explanation? Why a vague picture of a roadway with an "x" without an explanation? Who knows, I guess your suppose to read the owners manual. But let's say you bought your new car in April, you read the manual, you have lived in the car for three quarters of a year, how many people are going to remember a single sentence in the manual that you read 8 months ago.   Here's my idea, how about a warning light that says, Black Ice.
