Professional race-car drivers have long been gathering in teahouses and bowling alleys to devise an eco-friendly manner of racing. Today’s Groupon reconciles this dilemma with four Arrive & Drive races (a $80 value) and a pair of annual race licenses for two people (a $11.90 value) at K1 Speed. With electric karts and 1/3 mile of fast concrete, you can embrace your inner speed-demon without fear of pedestrian casualties, a depleted ozone, or trips to speed-heck.

Housing some of the largest indoor go-kart racing in the state, K1 Speed delivers high speeds without the fear of repugnant oil stains with a distinctly fuel-y odor. Going electric (http://www.k1speed.com/karts.html) is cleaner, faster, and makes a fearless lead foot seem the slightest bit more sophisticated.

K1 Speed uses a ProScore system to gauge your skills against your aggressive other-half, friends, or other racers in the neighborhood. Indoor go-karting offers all the enlightenment of real-life racing with the charm of low-emissions technology and safety of state-required safety measures. Sate your speed demon with a bowlful of racing topped with fresh tire tracks and paired with a tall glass of ice cold rubber smell.

A day at the electric-car racetrack is the perfect way to make new friends, become a Renaissance person, or display your ultracompetitive streak to a group of high-school students who follow you around after mistaking you for Kelsey Grammer.

Note: Today's Groupon is valid for one or two people over multiple visits.

Reviews

Insider Pages give K1 three stars, and Yelpers give it four:

• I've driven bunches of go-kart places and K1 is one of the best. Carlsbad, Irvine, and Anaheim are equally fun - and all different. The staff is courteous and respectful if you are; and very supportive if you are a respectful and qualified - even if aggressive - driver. – Gregory X., Yelp
• K1 Speed Carlsbad offeres [sic] a better driving kart than anything else I have been in. The instant acceleration allows the kart to be driven more like a real performance vehicle. – B H., Insider Pages
