Automobile-less?

I am contemplating selling my car. I do not particularly like my car. It's an SUV. And it didn't cost me a penny and it runs well and it's handy for carrying large loads... But gas in the PNW is over 3$ a gallon, I live 1.8 miles from work (20 mins walking). I live less than a quarter mile from one grocery store and about .5 miles from another. I live about 600 ft from a bus stop. and less than a quarter mile from the MAX (light rail) AND the trolley (in the other direction.)
I spend 45$ a month on insurance (how is it only 45$ for me? PERFECT RECORD for the last 15 years and I drive less (a lot less) miles than the average person in my geographic region, and my car is not new.)
I spend between 40-80$ a month on gas. I fill up only 20$ at a time and if I am not driving out to the suburbs often, that lasts almost 2 weeks. 2 weeks on less than half a tank of gas.
Anyway that's at minimum 85$ a month. A bus pass is 75$.
So economically I save between 15-50$ a month by not owning a car.
And I gain some exercise and the stressless-ness of not driving.

But I like driving. I like having a car. I like being able to carry large loads of stuff from, like, the nursery or home depot or the grocery store when we need to buy cat litter and cat food. I like the freedom to pop over to friends' houses or across town. Or to the coast.
But I hate the car I own.
I can sell it for about 4 grand and pay off some bills AND save money each month by not owning it.
And then I can save for a GOOD car, something I won't be ashamed of owning.
I can rent a flexcar if I need to go to home depot.
so, do I go carless in one of the best cities in America to do so? Am I ready, me, a California born and raised driver, ready to not have a car?
I don't know.
But it's on my mind, and I am leaning towards not having a car, for now.
