I have 3 major grocery stores (Safeway, QFC, Target) within 15 minutes walking from me. And at least 20 bars and restaurants within the same distance. Public transportation to downtown takes about 35 minutes, which isn't great, but it's okay. Uber works well if you need to be faster.
Wedgewood, Fremont, Queen Anne & Freelard all successfully resisted the mass redevelopment that Ballard has seen, compared to 15 years ago Ballard looks completely different while the aforementioned neighborhoods have not seen that same level of mass demolition.
Depending on where you live and where you're going, crossing the locks is a great way to bike downtown. Also sometimes the Fremont bridge route is going to be shorter. I hate riding my bike over the Ballard bridge, but I'm not sure I'd call riding on it "risking death".
Bike access within Ballard is pretty great since the hills are a bit more manageable than in other parts of the city.
All that aside, it's pretty easy to live in Seattle and not have a car, being able to walk to groceries, bars, restaurants, parks, etc.
I would highly encourage avoiding the Ballard Bridge. IMO it's very dangerous.
Walkability in Ballard is pretty good. We're within 15 minutes walking distance of QFC and the bar/restaurant area south of Market. That said, I prefer to drive to the grocery store so I can go infrequently and buy more at once.
I really don't mind the short jaunt to the Fremont bridge, but it does add some extra travel time. Never ride on the Ballard bridge; it just doesn't have anywhere for bikes to be. The sidewalks are too narrow and unprotected from traffic, and the primary traffic lanes are going 40+ mph. That whole thing needs to be replaced for the 21st century, although there may be some resistance as it's a nationally registered "historic place."
Let’s us Stockholm as an example: 100 metro stations and 170+ suburban rail stations, 60 light rail stops, on 2.3 million people in 6,519.3 km2 (2,517.1 sq mi).
San Francisco (Nine county, Bay Area), 33 metro stations, plus 87 additional metro stops about 200 station (ACE, Amtrak, BART, Caltrain, SMART, and VTA), on 7.75 million people, In 6,966 sq mi (18,040 km2).
The station density is nearly 2.5 times higher and on less than half the population.

LA has no unified bus system. It has multiple ones and its super confusing. Each bus makes a stop nearly every minute, making every ride impossibly long. Lack of bus lanes make for shitty traffic stuck trips as well.
It's the same in London. That's why for longer rides you take the tube. Buses are for shorter rider or from getting from/to tube station.
San Francisco is only about 7 miles wide. You can walk from one side of the city to the other in about 2 hours. When I lived there, I walked almost everywhere. The only times I did otherwise was when it was a really long walk (over 45 minutes), or I needed to be somewhere fast. The bus will not get you anywhere fast, it's only about twice as fast as walking. I think that's why a lot of people use Lyft. The buses are actually quite nice inside imo, they're just slow. Plus the stigma that only poor people ride the bus.
