First and foremost--What will you do for stretches of inclement/cold weather? If carpooling with DW is an option for such days/weeks, then you could consider the bike/scooter/motorcycle. If you think the carpool would get old or be too much trouble, you've already made the car/no car decision. Then it's just a matter of how much car to buy.
Days of rainy weather and/or cold temps are a primary reason people refuse to give up a car, even if they live close to work (and 6 miles one way is close in my book). In the sunny weeks of summer, our company's motorcycle parking and bike racks can get full on some days. If it's threatening rain or less than 50 degrees, there might be 1-2 motorcycles and one other bike besides mine.
One other thought--If you decide you're definitely dumping your lease for another option and you want to give a non-car option a try, then you're in a great time to do so. You can buy a car any day of the week, but once you buy one, you've set yourself up psychologically and financially to stick with that option. When our DS1 bought one of our cars, I decided to start biking to see how we would work as a one-car but two-jobs family before we bought another car. Several years later we're still a one-car family, I've racked up thousands of miles on the bike and lost a lot of weight. We still have the occasional difficulty managing transportation/schedules, but we're satisfied overall and don't have any plans to change back to that two-car setup again.
