Yeah. I took the bus in NY and SF and I’m also not sure why the complained. Maybe because I’m a tourist but especially in SF I had always nice interactions with the driver. Mind you I took the Bus in the City Centers. Is it that much worse in the outskirts or is it just the concept of taking a Bus with multiple other people the problem?

In SF it really depends on which line you're on, and a bit of luck. In my experience the 9 was the worst. I didn't ride that one often, but almost every time I encountered something ridiculous. One time a guy rolled a blunt and started smoking it on the bus. Another time a guy in a wheelchair spilled a bottle of booze that then ran up and down the floor of the bus. I got off early several times when an obviously crazy homeless person got on and started silently staring me down.

But even popular commuter routes like the 38 can get pretty dicey. One time a guy was blasting music out of a bluetooth speaker. He had headphones sitting on his neck, so I asked him to use his headphones instead. His response was to get in my face and start yelling, threatening to beat me up. Everyone around us stepped away and ignored us. Apparently the next stop was his, so he got off while threatening to jump me if he ever saw me again.

If you take public transit in the bay area regularly, you are almost guaranteed to have some very unpleasant experiences.

We were discussing riding the bus to a place that depending on traffic is a 20 minute car ride from SF, or a 2 hour car ride in the worst case scenario traffic.

There are a few bridges that connect SF to other places across large bodies of water, the Bay Bridge and the Golden Gate Bridge. These bridges do not provide a dedicated lane for the buses. These bridges act as a choke point for traffic. As a result, the buses are not reliably on time, because the traffic is hard to predict and it depends on whether or not people have a car accident that evening.

As I mentioned in another comment, these buses do not have bathrooms inside. So you are spending an unpredictable amount of time standing at an unsheltered bus stop, often with no bench to rest on, followed by an unknown amount of time on the bus.

The buses come infrequently enough that if you go find a restroom after waiting a while at the stop, and the bus comes while you are gone, it will be a decent chunk of your life spent waiting for the next bus to come as well.

This might be fine if you're on vacation and you just wanted to explore the Bay Area, but if you live here and work here, this is just too much time!

If you have a car, there is essentially no upside to taking the bus in this situation, which means if you are greedy and choose to drive instead you contribute to traffic by taking up more space on the road.

In contrast, if you choose to take the train, you know exactly how long the trip is going to be, because there's no variable traffic disrupting the schedules. It's predictable. It's convenient. Sometimes the train might get stopped for one reason or another, but the trains come so frequently that this is rarely an issue.

Before your trip, you're also inside a train station, which is sheltered, has seating, and even often has bathrooms.

There's a sign telling you clearly how long until the next train arrives, you don't have to count on something on your phone to find out.

It's pure snobbery
