Wife took me to
Autobahn Indoor Speedway near us in Manassas, VA this past Saturday. Had an absolute blast, the carts hit 40mph once they turn the speed up. You start around 50% power and by the 4th lap of your 14-lap race you're at 100%. Working on organizing a group event with my local BMW (DC area) crew and some other friends. They're nation-wide, I highly recommend checking them out if you have one nearby. Only recommendation would be to go with enough people that your group takes up the whole track for a race so you don't have any non-competitive folks on the track with you lol.
