lol yeah right. i would say that my phone is too valuable to me for thatbut i have an application on it that uses gps for a speedometer and will give me an average speed and a maximium speed. according to both my 07 jetta and my 91 crx, it only reads 2mph slower than what my cars speedo reads. at any speed...... appearently my 07 jetta is governed at 132mph and my crx si guage stops at 125 but with the jdm b16 and many other mods the needle just keeps going.
