Are you personally offended by someone sharing their experience of living without a car? Maybe people in the writers situation have never reflected about this lifestyle before because they take the car for granted and now he inspired people to try to live without a car. That doesn't mean that everybody needs to stop using their car – especially if they are dependent on it.

Whenever someone reacts strongly just because someone else share their personal experience of different life choices whether it's ditching the car or going vegetarian or anything progressive I can't help think it's their own guilt speaking.
