Professional race-car drivers and the environment have had a long-standing feud since engines create harmful pollutants and Planet Earth notoriously uses illegal weights to maintain speed through turns. Today’s Groupon reconciles this dilemma: for $44, you get four Arrive & Drive races (an $80 value) and a pair of yearly race licenses for two people (an $11.90 value) at K1 Speed in Redmond. Today's Groupon is also valid for one person over multiple visits.

Housing one of the largest indoor go-kart racing centers in the state, K1 Speed delivers high speeds while bypassing the repugnant oil stains and distinctly fuel-y aroma of petroleum-powered contests. With electric karts and 1/5 miles of fast concrete, you can embrace your inner speed demon without fear of pedestrian casualties, a depleted ozone, or soggy socks from powerboat trips down the river Styx. During each Arrive & Drive session, racers suit up and race against the clock or up to 12 rubber-burning rivals for 14 laps (about 10 minutes). Instruction for first-time riders is provided, as well as head socks and helmets for all racers.

Yearly licenses grant gear gladiators a newsletter subscription, a complimentary race on the owner's birthday, access to the facility's online database of racing results, and more. K1 Speed records personal records and times with a ProScore system to gauge your skills against your aggressive friends, your Mirror Universe doppelganger, or local robots unfairly equipped with permanent lead feet.
