GPS tracker with capability to drive a speedometer ?

my question is, i understand that people have made GPS tracking devices for themselves and maybe their vehicles but has anyone produced one that has the capability to be able to drive an electronic speedometer or a stepper motor that could in turn drive a mechanical speedometer?

Hi, class questions should be related to class material-- this introductory Arduino class covers basic input/output and beginner coding, but not complex sensing like GPS or complex output like motors. =D

Your idea reminds me of the Speed Vest:

And someone created this Instructable about an Arduino GPS speedometer:

Hope that's helpful!
