Advice from anyone using Pittsburg/Baypoint bart

Hey everyone,

Not rage related, but thinking about moving to brentwood and looking for info about the station.

What time does the daily parking fill up?
Is the travel time to SF really only an hour?
What is traffic like on 4 during morning and evening between bart and brentwood
Any info regarding park and rides (how long does it take to get to/from bart, parking availability/cost)
any recommendation for ride sharing/carpooling from brentwood to bart?

Thanks in advance.
