How do you think most East Bay commuters are getting to San Francisco?
Personally, I take casual carpool, https://sfcasualcarpool.com/, to work and a transbay bus home. Total cost is $6.50/day, which is cheaper than commuting by Bart, and because I live 30 mins walking from Bart, it is also much faster.
South city may as well be the middle of nowhere transit-wise but the difference between taking BART to Market St vs SSF isn't all that big.
I disagree with your last statement. BART is 4 miles from oyster point, so you would have to take a shuttle. I'm going to assume that is at least 20 minutes more, if I'm being generous. So, for me, that would equate to about a 90 minute commute each way, at a minimum, where as a commute to Market street via BART would be about a 50 minute minimum. 80 minutes per day is not a trivial amount of time for me.
Overall, I'm not sure what the argument here is. That a lot of people take BART? That we should be ok with more commute time?
I'm struggling to figure out how a one hour increase in commute time isn't a big deal. Without even discussing the local bus.
Bay Area needs more robust interconnected public transit, and higher density housing near transit hubs.
