Isn't a 15 minute walk the definition of walkable ? That's almost the perfect mix of time convenience and health benefits.
Perhaps all of the bad weather in Fremont tips the scales for you ?
EDIT: I mean walk around under the Grimmer underpass, not dart across the freeway obviously.
One parking warden can cover a large area, residents get a permit, visitors only need to pay for one hour of parking.

When I lived far out in the suburbs there was a commuter train once an hour and I could always count on being able to drive the freeway faster, even in traffic even though it was miserable.
EDIT: Yeah, this is flippant, but far as I can tell it's the truth. Policymakers are well aware that public transit is often not the most attractive option, and are working to bring it to the top of your list of options by degrading driving until it's worse. Congestion pricing, parking scarcity, reducing road throughput, etc. I guess in principle some of this might make buses more attractive, but not trains.
Stuff like congestion pricing isn't intended to increase use of public transport (that's a side effect), it's intended to reduce traffic and make driving "better" (by pricing lower-income folks out of it, but that's generally how "better" works in the U.S. anyway).
BART is in a really incoherent place with respect to this. It definitely wants the number of station-accessible parking spaces to shrink, but its plans for the surrounding areas include basically everything except housing for BART commuters.
Offices, retail, housing for disabled homeless veterans, housing for seniors, housing for unemployed people, community centers, maker spaces for underrepresented groups, etc. Anything and everything but market rate housing.
A "transit village" plan was partly executed at Macarthur, except predictably, the market rate housing part fell through. Another "transit village" is going up on the parking lot at West Oakland (best station to drive to - sits on an underutilized freeway, parking still available at 9:30am in adjacent private lot, departures every couple minutes, and only 7 minutes to Embarcadero). The transit oriented development will include, again, everything but market rate housing.
Far as I can tell, BART is not trying to bring station users any closer, it just wants them to switch to bicycles. (Fuck that shit. Right before boarding a crowded train is the worst possible time to pedal a few miles uphill. I'll pay whatever it costs for the remaining privately owned parking, and when I can't, get out of this hellhole. I run 4 times a week, but it's sort of the whole point of civilization to me that exercise is decoupled from transportation).
