After driving cheesy indoor amusement park electric karts, I was a little apprehensive driving electric karts. However, in the last week I have driven electric karts at two different indoor tracks. One just outside of Chicago and one just outside of Minneapolis. All I have to say is wow. Not only do these karts perform, you also get performance data. Info about your laps, comparison to other drivers, etc. They also run leagues and grand prix's. If you like to drive, check it out.
