Something you buy with your own money doesn't shout "privilege" as loudly as something you're given for free. If Google was handing out cars to their employees, the comparison would be more apt.
> Like, you know, almost everyone, including the poor.
Lots of people who live in cities don't have cars, including many of the not-poor. Many (most?) of these people use public transit. Having access to a robust public transit system is generally seen as one of the benefits of living in a dense urban area.
> What in the world is wrong with not taking public transportation? It somehow makes you arrogant, conceited and evil?
No, it makes you look like you're isolated in a cushion of comfort specifically designed to protect you from having to deal with your neighbors. That's not evil, but it's also not the best way to make friends and otherwise seem engaged and non-aloof.
