• How long should I go without a car?
• If we take a colleague in our car to an event, does that count as carpooling or should we take a "stranger"?
• Does driving an electric car count or not?
• Does someone who never takes a car during the 3 weeks of the challenge validate the challenge?
• Does someone who walks to work every day (about 10-15 minutes) validate the challenge?
• My carpooler is currently teleworking due to Covid, can I score points for this challenge as I usually make the effort?
