Curious WheelNavi Gadget Attaches To Steering Wheel, Tells You You’re Turning But Why? Are We Missing Something?

It's been a while since we've come across what we would deem to be a
'curiosity' but this WheelNavi gadget certainly fits neatly into this
category as its sole purpose appears to be to relay just how many
degrees you're turning your car's steering wheel - the device fixes to
the steering wheel itself thanks to an adhesive backing - but quite why
you would need such a device wholly escapes us.

Perhaps we're missing something here, and we don't doubt that you'll let
us know if we are, but what concerns us is the fact that, if you're
employing and using this device, then whilst staring at it to verse
yourself with just how many degrees you're turning you steering wheel
you're not actually looking through the windshield which, in anyone's
book, is not an especially good thing.

The similarities between this device and an aircraft's Turn and Bank
Indicator (shown below) areย striking.

Undoubtedly up there with the likes of the likes of the CallMe Prism-I,
the WheelNavi comes in four flavours, retails for around $21/pound
sterling11/e14 and we're truly stumped as to why anyone would need such
a device.

Perhaps you can offer us some insight?
