You're going from a local commute to bart -> walking to the office, to a local commute to bart -> going to a station that is skipped by 3/4 of bart lines (ie requires an xfer for Antioch, Pleasanton, or Fremont) -> a shitty bus. NB: Bart is ass and generally is too incompetent to align train and bus schedules.
This adds probably at least 45 minutes each way for anyone coming from SF or East Bay locations and using public transit. It's an enormous downgrade.
I don't think what you're saying contradicts anything that I said -- I said that the move to SSF makes it more difficult to commute via BART, but that it was too strong to say that it "eliminates" the possibility of doing so.
In any case, I really suspect that if companies keep moving to the SF Bay Area and keep growing, they're going to have to start moving to places that are out of the city. The rent per square foot in SF is approaching $85/ft^2, the highest it's been since the original dotcom boom; downtown San Jose is around $60/ft^2, better but not that much better. But places like San Ramon, Fremont, non-downtown San Jose, and yes, South San Francisco are around $30/ft^2. Some would argue that staying in the Bay Area at all is silly for tech companies at this point; while I don't think I'd make that argument, if I had several hundred employees to find space for, I just don't think I'd do it in the City.
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.
