The suburban model doesn't allow people to live close to any of the places they go. I too dislike wasting my time traveling, but I don't have to: I can walk five or ten minutes to the grocery store, dentist, park, restaurants, etc. I end up walking a lot over the course of a week, and personally I also bike to further destinations (a lot more people would here too if there were protected bike lanes like you mentioned you want). My travel time _is_ my exercise time - no need to spend time on extra walks to accomplish that, and there's interesting things around me when I go from place to place. The subway or commuter rail can take me further away faster than a car when I need to go somewhere distant.
But I'm lucky I can afford to live in a part of Chicago that hasn't been totally disinvested in over the last half century, like a lot of the city has. The state didn't pave a highway through the middle of it like they did to other - mostly black and brown - parts of the city to convenience suburban drivers.
The suburban model that works just fine for you comes at a cost to society. We need to reckon with that and build more places where people aren't forced to drive for their day-to-day necessities and desires.
