Doctors report that every summer, an alarming number of Americans feel the "need for speed," which in turn is the number-one cause of rash-action rashes. Treat your ferocity for velocity with today’s Groupon: for $25, you get two adult races at Podium Raceway Hawaii in Kapolei (up to a $50 value). Save time by printing and signing the safety waiver before arrival.

Housed inside a 44,000-square-foot enclosed venue to protect clients from inclement weather and Five-0 speed traps, Podium Raceway Hawaii’s indoor electric-kart racing track injects slow-lane lives with a concentrated cocktail of velocity, competition, and proper turn signals. Up to 12 drivers strap into any of 35 high-performance European machines that jump from 0 to 50 miles per hour in three seconds flat, then pit themselves against one another during two 14-lap tours through the hairpin turns and desperate straightaways of the quarter-mile raceway. Helmets, signal flags, and a brief kart briefing keep everyone on the same page of the safety manual. Podium Raceway Hawaii maintains remote control over all its karts to enable emergency stops and prevent accidents from road rage, negligent merging, and pesky deer crossing the track.
