Maybe not, but some of us find it vastly preferable to being crammed in with others on public transport. So don't tar everyone with your particularly preferences thanks.
On a side note, BART is probably going on strike this week, which means that an hour BART commute is soon going to turn into a 4 hour commute when the traffic on the highways double.
At that point it becomes a lot preferable to spend 1h on a train somewhere reading a book / catching up on news or email, rather than getting enraged in gridlock traffic without doing absolutely anything productive (yes, you could theoretically do radio/audiobooks).
Until then, I'll always prefer driving/walking/biking/anything. Unfortunately, I'm in a situation where I can't drive now, and I have to deal with an awful San Francisco public transit system that does 0 of the things I listed.
The problem is that you live in San Francisco.
The biggest problem in that list (safety/perceived safety) has more to do with the city than the transit system itself. It's not a brokenness in the transportation system (though more can be done to curb it, certainly), it's a brokenness in the society it serves.
It's always a little depressing to think about how so many other cities - both bigger and smaller - on this continent put the transit of San Francisco utter, complete shame.
But now there are a ton of pretty awful immigrants from the Middle East who harass women, destroy property, and threaten anyone they dislike... which is quickly making European cities very unpleasant places to live. I wouldn't be surprised if Europeans start their own version of white flight away from their cities.
On many bus routes the conditions can be positively third world. Graffiti everywhere - seats, floors, windows. Human excrement. Urine. Addicts. Homeless. MUNI buses are one of the less fortunate places you can find yourself anywhere.
Having lived there in the past, I can sympathize with residents who want to drive, or take Ubers everywhere. The public transit in the city can be a very foul experience - though this is largely a reflection of the city rather than the system itself.
We focus on crime, because it's easy to lash out at order breaking down and can relate to being harassed by the small percentage of Muni riders who can genuinely be considered subhuman refuse. In reality, though, SF has several times as many annual traffic casualties (around 3000, from some rudimentary Googling) as crimes reported on Muni (around 1000).
That latter figure has some factors that may suggest undercounting (it's reported crimes, and I can see how people might have so little faith in Muni that they don't bother reporting it) but also some that suggest overcounting (it includes fare violations and eating on the bus).
Muni certainly needs to be cleaned up, but let's not get ahead of ourselves: you're much more likely to die via automobile in SF than being shot or stabbed on the Muni. I wouldn't be surprised if you're more likely to be killed being hit by a Muni than murdered on the Muni.
For various reasons, it is still much cheaper to live in the suburbs and commute into the city than to live in San Francisco. I wonder how the other walkable cities are fairing.
Perhaps when people buy homes, they tend to not buy a new car at the same time - prior to the housing crisis, many people bought lots of homes. Then the market collapsed and they lost their money, further reducing the number of new cars bought.
Oddly enough, some 2000-model-year used Hondas and Toyotas did not depreciate in value between 2010 and 2013 because the used car market heated up.
The suggestion that destroying operational vehicles would be a net gain for the economy is an excellent illustration of the broken window fallacy.
Cash-for-clunkers helped middle and upper-middle class people, including some friends of mine, who wanted to buy new cars. The cost of the program was born mostly by poor people, as is often the case.
Or starve, as the case may be.
At the very least, car sharing is a step in the right direction. Eventually as the Google car becomes reality, I hope that the # of cars on the roads is reduced to a bare minimum and we don't need to drive / pay people to drive any longer, and free up a lot of human talent to do something more productive.
