I have bought an Arduino UNO R3, GPS expansion board with an external antenna and memory slot, 3-axis gyroscope. I want to build a product that can accurately measure the acceleration, positive and negative G-forces and save it to the memory card, which then is possible to analyse. 0 -100km / h 70-140km / h, 100-150km / h, 100-200km / h and also log maximum top speed. Positive and negative G-force. It shall also take into account the upward/downward slope and view it in %. It should also be able to use Google Maps or similar and to show you where you drove. Compensation is paid, of course.
A product that i like is this (its very expensive though):
