my wife came bundled with a car from the day i moved in with her back when she was still my fiance. i had been a LCF bachelor for over a decade prior to that.
she's not a LCF person by nature, and now that we have a 3 and a 5 year old, there are absolutely times when owning a car just makes life easier.
she works from home >90% of the time, and i ride my bike to work. i also have good transit options for when i don't.
i could conceivably just drive our car to work the vast majority of days because my wife rarely uses it, but riding my bike is 8 billion times more fun than driving around in chicago rush hour traffic.
TL;DR: if you like bike commuting and it works for you, then ignore the wife's new car and keep doing your thing.
