Go-karts provide the drama of street racing without the legal woes of infringing on Vin Diesel’s copyrighted pensive pre-race stare. Steer some serious speed into your life with today’s Groupon: for $21, you get 40 indoor go-kart laps at 401 Mini-Indy (up to a $56.60 value).

401 Mini-Indy drops speed seekers into nine-horsepower, four-point-safety-harnessed go-karts that they weave and whistle along the indoor course’s straightaways and 180-degree hairpin turns. 401’s experienced staff, which includes full-time mechanics, outfits each driver with a helmet before launching them into road-ripping battle with a regulation-sized catapult. With computerized scoring and timing, every race records brag-worthy statistics to tout to friends, strangers with honed listening skills, and family. The fully ventilated arena and the protective guardrail and bumper system safely secures auto adversaries from start to finish, sending them home with a sound repertoire of grooving, drafting, and cut-off artistry that can serve them well the next time they exit a crowded office elevator.
